Choose the music before you open OBS. Use YouTube Studio’s Audio Library, or a track whose written licence expressly covers livestreaming and the resulting replay, then capture it as a separate OBS source and include it in the main stream mix.

A clean live mix does not remove copyright risk after the broadcast. Test the live sound and the archived replay separately, and keep records of the licence or attribution you relied on.

Choose music with rights for the livestream and replay

The first decision is not the volume level. It is whether you have permission to use the music in the way you intend. A gaming replay normally involves two uses at once: the track is heard during the live broadcast, and it remains in the recorded video on YouTube afterwards.

Look for written terms covering both livestreaming and archived video. If the channel is monetised, check the terms for monetisation and revenue sharing as well. Also check territory, duration, attribution, and whether the rights holder can allowlist your channel in Content ID.

A track labelled “free” is not automatically cleared for a YouTube broadcast. YouTube itself warns that music found online with a free label can still be flagged by Content ID. A credit in the description may satisfy an attribution condition, but it does not create permission where the licence does not provide it.

If you use a game soundtrack, treat that as a separate rights question. The fact that the music plays inside a game does not by itself establish that you may rebroadcast it. Check the game publisher’s current policy and any in-game audio options, and do not assume that a gameplay permission also covers every musical recording.

For a practical comparison, record the answer to each question before adding a track:

Question What to confirm Why it matters
Livestream Does the licence expressly cover live streaming? A video-only licence may not cover a live broadcast.
Replay Can the recording remain publicly available after the stream? The archive is another use of the music.
Monetisation Are monetised streams and replays allowed? Some licences allow personal use but restrict commercial use.
Attribution Is a particular credit required? Missing attribution can breach the licence even where use is allowed.
Content ID Can the owner allowlist your channel? A licence may not stop automated detection or a live interruption.
Evidence Can you retain the receipt, terms or download record? You may need to explain your rights later.

YouTube’s copyright claim versus strike explanation is useful when you are deciding how to respond to a notice. It does not replace checking the licence before the stream.

Creator Music needs particular care. At the time of checking, YouTube’s Creator Music FAQ states that its licensing does not support live content. Do not assume that a Creator Music term for an uploaded video covers a gaming livestream and its replay. Check the current availability, eligibility and individual track terms in YouTube Studio before relying on that catalogue.

Find suitable tracks in YouTube Studio Audio Library

For a YouTube-focused channel, the Audio Library is the clearest starting point because the catalogue is presented inside YouTube Studio with track-specific information. Open the library, search or filter by genre, mood and duration, and inspect the attribution requirement before downloading anything.

YouTube says that music downloaded from its Audio Library is copyright-safe on YouTube and will not be claimed through Content ID. That statement applies to the library’s own catalogue and does not mean that every track elsewhere with a similar name or description has the same treatment. Check the individual track information in Studio and follow any displayed attribution instruction.

If a track uses a Creative Commons licence, copy the attribution text shown in Studio rather than writing an approximate credit. Put it in the live stream description or the replay description as appropriate. Keep a copy of the track information with your project files so you can identify what was used if the replay is reviewed later.

The Audio Library is also practical because you can download the file before the broadcast and avoid depending on a separate music website while you are live. Store the selected files in a clearly named folder, such as gaming-replay-music, and keep the attribution text beside them. This reduces the chance of selecting a different version by mistake.

The YouTube Audio Library guidance explains where to find the catalogue and how attribution is shown. Read the current page rather than relying on an old screenshot, because Studio menus and catalogue terms can change.

If you choose an external provider, read its licence in full. Confirm that the permission applies to YouTube, live streams, replays, your country, and monetisation if relevant. Keep the invoice, licence page or account record. YouTube may not know that you purchased rights from another provider, so an external licence does not necessarily prevent an automated claim.

Capture the music application in OBS

Add the music as its own audio source in OBS rather than letting it disappear into a single Desktop Audio channel. Separate capture gives you a dedicated fader, mute control and meter for the music. You can then lower the track without lowering the game or your microphone.

On supported Windows versions, OBS provides Application Audio Capture for a selected application. Open the Audio Mixer or Sources area, add the application capture source, and select the music player. The OBS Application Audio Capture guide describes the supported Windows requirements and the available capture methods. The exact labels can differ between OBS versions, so use the current interface on your computer.

The important routing rule is to avoid capturing the same application twice. If the music player is captured through Application Audio Capture and also through global Desktop Audio, OBS can send both copies to the stream. That can create a louder signal, phasing, or an audible echo. OBS recommends disabling global Desktop Audio when it would otherwise capture the same application.

After adding the source, start the music briefly and watch the music meter. You should see movement on the dedicated source and not an unexplained second copy on Desktop Audio. Stop the music before going live if you are still configuring the scene, then restart it only after the routing is clear.

On macOS or Linux, the capture method may differ from the Windows application-capture workflow. Do not assume that a Windows tutorial maps directly to your system. Use the capture method available in your current OBS installation and verify the result with headphones or a separate playback device.

If you are also running a pre-recorded 24/7 channel, keep the source arrangement understandable. A guide to starting a 24/7 YouTube stream from pre-recorded videos can help with the wider broadcast setup, but the music still needs its own rights check and audio source.

Balance music, gameplay and voice in the mixer

Once the music is captured, balance it against the sounds that carry information. Viewers need to hear speech, important game audio and the music without continually adjusting their device volume. There is no universal fader position that works for every game, microphone and track.

Start with the game and microphone at their normal speaking and playing levels. Bring the music in quietly, then listen to a section containing dialogue, menu sounds and louder gameplay. If the music competes with the voice, lower the music rather than asking viewers to tolerate a crowded mix.

Watch the meters while testing, but do not judge the result from meters alone. Two sources can show similar activity while one is more prominent to the ear. A bass-heavy music track may feel louder than its meter suggests, while a bright game sound can cut through at a lower average level.

Use headphones first, then check on a phone or another small speaker if possible. A mix that sounds balanced on studio-style headphones may make the music too dominant on a phone. This second check is especially useful for devotional, lo-fi or ambient channels where the music may remain present for a long period.

Keep the music source separate even if you expect to use the same level every time. A dedicated source lets you mute the track quickly if the licence is questioned, if the player changes track, or if the game becomes unusually loud. It also makes troubleshooting easier because each channel can be checked independently.

Do not add processing simply because a tutorial shows it. Compression, noise suppression and filters can alter the relationship between voice, game and music. First establish a clean source and a sensible balance. Add processing only when you can describe the problem it is intended to solve.

Send the music to the main stream mix

A source appearing in the OBS mixer does not automatically mean that every output will contain it in the way you expect. Check that the music is enabled in the main stream audio mix and is not muted or excluded by an advanced audio setting.

For the ordinary YouTube live output, the key result is simple: the stream mix must contain gameplay, voice and music. If the music is assigned only to a separate recording track, it may not be heard in the normal replay when YouTube plays the primary track.

OBS’s multiple-track guidance explains why this distinction matters. Separate tracks are useful when you plan to edit a local recording, but common video players play one audio track at a time. If you will publish a recording without editing it first, assigning all intended sources to track 1 is the safer arrangement for the resulting file.

You can still use additional tracks for editing if you understand what each track contains. For example, a local recording might have a complete mix on track 1 and isolated sources on later tracks. That gives you options in an editor, but it does not change the audio already sent to YouTube during the live broadcast.

Before the test, write down the intended path: music player, music source, OBS mixer, main stream mix, YouTube live output, archived replay. If one link in that chain is missing, the music may be audible in your headphones but absent from the public video.

Test the live sound and the resulting replay

Make a short private or otherwise limited test before relying on the setup for a full gaming session. The purpose is not to prove that the track is free of copyright risk. A test checks whether your routing and levels behave as intended.

During the test, confirm four things:

  1. The game audio is present.
  2. Your microphone is present and understandable.
  3. The music is present at the intended level.
  4. The music is not duplicated through Desktop Audio or another source.

Listen to the live output from a separate device if possible. Do not use only the OBS preview or the same headphones connected to the streaming computer. A second device can reveal a missing source, excessive volume or a delay that is difficult to notice while you are operating the game.

After ending the test, open the archived replay and check the same sections. YouTube’s replay is the relevant result for viewers who watch later. Confirm that the beginning, a normal gameplay section and a louder section all contain the expected mix. If the replay is silent or missing one source, return to the track routing before starting the full stream.

Check the replay’s description as well. If the track requires attribution, make sure the credit is present and correctly copied. Retain the local recording if you need an independent reference, particularly before using YouTube Studio’s editing tools on a claimed video.

If your wider setup needs constant recovery, review how it behaves after a disconnect or restart. The practical issues in 24/7 live stream auto-restart and recovery are separate from music rights, but a restart can also alter which application is playing and whether OBS captures the expected source.

For creators who do not want a computer running all night, StreamNeo removes the need to keep the local machine switched on for an uploaded video-based YouTube stream, but you should still prepare the file, stream key and music permissions before starting.

Understand live scanning and post-stream Content ID claims

YouTube scans live streams for third-party content. If it identifies material, the live broadcast may be interrupted or terminated. The archived live video can also receive a Content ID claim after the stream ends. These are related risks, but they are not the same check at the same moment.

A successful live broadcast therefore does not prove that the replay is clear. The music may pass through the live mix and still be identified later when the archive is processed. Conversely, a licence may give you permission to use the track while the rights holder’s Content ID settings still cause an automated notice.

If you have a third-party licence, YouTube advises asking the rights owner to allowlist your channel through Content ID. This may reduce interruptions caused by an authorised use, but it is not a substitute for reading the licence. The rights owner controls whether and how allowlisting is offered.

If the replay receives a claim, read the notice before taking action. YouTube Studio may offer options to trim the claimed segment, replace the music with an Audio Library track, or mute the claimed song or all audio in the affected segment. Since June 2025, YouTube says saved Studio edits cannot be reverted, so preview the result carefully and keep an original local recording where possible.

Do not dispute a claim solely because the track was described as royalty-free. Dispute it only when you have a genuine basis, such as permission that covers the use and evidence to support it. If the licence does not cover livestreaming or the replay, replacing the music may be the more appropriate solution.

YouTube’s copyright issues with live streams guidance explains the platform’s treatment of third-party content during live broadcasts. Review the current official guidance when a claim or interruption occurs, because policies and Studio options can change.

Use a repeatable pre-flight check

Before each longer stream, run through the same short sequence:

  • Confirm the selected track and its licence or Audio Library terms.
  • Copy any required attribution into the planned description.
  • Open the music player and select the intended file.
  • Check that OBS captures the application only once.
  • Check the music, game and microphone meters separately.
  • Listen to the main stream mix from another device.
  • Confirm that the music is assigned to the main stream output and, if needed, recording track 1.
  • Keep the licence evidence and original recording available.
  • Review the replay after the broadcast for both sound and claims.

If the upload connection is also uncertain, test that separately rather than changing several parts of the setup at once. The checks in how to check whether your upload speed is enough for YouTube Live address delivery capacity, while this article focuses on the audio path and rights.

The most reliable workflow is deliberately ordinary: choose music with the intended permission, capture it once, mix it beneath the important sounds, include it in the main output, and inspect the replay. That process reduces avoidable audio faults without suggesting that a test or a particular catalogue can prevent every Content ID decision.

Before committing, compare the operating options on the pricing page. When the file and channel are ready, start free — 24-hour trial, no card.

FAQ

How do I add music to my gaming stream in OBS?

Add the music player as a separate application audio source where your operating system and OBS version support it. Check that the same music is not also captured through Desktop Audio, then balance the dedicated source with gameplay and microphone audio.

How do I keep music in my YouTube live replay?

Send the music to the main stream mix, not only to an additional recording track. Run a short test, end it, and listen to the archived replay from another device before depending on the setup for a full broadcast.

Can I use Creator Music on a live stream?

Do not assume that a Creator Music licence covers live content. YouTube’s current FAQ, as checked for this guide, says Creator Music does not support licensing for live content, so check the current terms in YouTube Studio before choosing a track.

Can a replay receive a claim even if the live stream worked?

Yes. YouTube can scan the live broadcast and process the archived video separately. A successful live mix does not remove the possibility of a later Content ID claim, so keep your licence evidence and review the replay after the stream ends.
