For a prerecorded store promo on YouTube Live, send the promo and its background music together as one programme from an encoder such as OBS Studio. You can keep the music as a separate OBS source for independent volume control, or combine it with the promo in an editor before streaming.
The first check is not a volume setting: make sure the music rights cover a store promotion, live streaming, relevant territories and any replay that will remain available. YouTube scans live streams for third-party matches, and a stream can be interrupted even if you have licensed the track.
Confirm the music rights before you mix
“Background music” describes where a track sits in your edit; it does not change what rights you need. Before adding a song, establish that the store can use it in promotional content and that the permission also covers distribution in a YouTube livestream. If the broadcast will be archived, check that continued availability of the recording is covered too. Permissions may be limited by territory, duration, platform or type of use, so read the terms for the specific track rather than relying on a broad label such as “royalty-free”.
YouTube’s livestream terms put the responsibility for necessary rights on the person providing the live content. The terms say: “You represent and warrant that you have all necessary rights for the exploitation of the Live Content on the Google Services throughout the world, including, without limitation, music licensing rights from artists, record labels, publishers (including public performance licenses) and any other royalty participants.” Read the current YouTube livestream terms and check the licence with the rights holder or supplier for the actual planned use.
The YouTube Audio Library is a practical starting point for tracks YouTube says it knows to be copyright-safe on YouTube. Check the individual entry: some tracks use a Creative Commons licence and require attribution in the description. That does not automatically answer whether a track covers every part of a store’s broader campaign, including use outside YouTube. YouTube says it cannot provide legal guidance about off-platform use, so confirm the scope if the same promo will appear in adverts, social posts or in-store screens.
Keep a simple record with the track name, source, licence terms, date checked, required credit and the intended use. Save the permission or receipt alongside the promo project. This will not prevent a claim or replace the platform’s processes, but it gives you something specific to check if a notice arrives. A useful overview of the words that tend to appear in this process is our guide to live streaming terms in plain English.
Choose separate sources or a pre-mixed video
There are two straightforward ways to send the music. In the separate-source workflow, OBS plays the promo and music independently, then combines them into the outgoing programme. In the pre-mixed workflow, an editing app renders one video with the music already mixed into its audio. YouTube receives the encoder’s combined audio and video either way; the difference is where you do the mixing and how much adjustment you want during the broadcast.
| Workflow | Useful when | Trade-off |
|---|---|---|
| Separate OBS sources | You may need to change the music level without changing the promo sound | You must check source routing, playback and looping in the scene |
| Pre-mixed video | The final mix is settled and you want one file to play | A level change usually means editing and exporting the video again |
Choose separate sources if a spoken offer, product demonstration or other sound in the promo needs to remain clear while the music sits underneath it. It is also easier to mute or adjust the music during a live session. This flexibility comes with a check: make sure you have not left the promo’s original music playing under a second music source by accident.
Choose a pre-mixed video if each promo has a fixed, approved soundtrack and you do not expect to adjust it live. You can watch the export as a single finished piece before loading it into OBS. If a spoken price or store detail is covered by the music, however, you will need to return to the editing project and make another render rather than simply move one fader.
The promo’s intended behaviour matters too. For a one-time presentation, let it play once and plan what the viewer sees afterwards. For a repeated store loop, check whether the promo should repeat and whether the music should continue seamlessly at the join. Our guide on looping a video on YouTube Live covers the playback side; the audio still needs its own listening check.
Add the promo and music in OBS
In OBS, create a scene for the store promo. Add the local video file as a Media Source and select the file you have checked. OBS’s Media Sources documentation describes support for common media files, including MP4 video and MP3 or WAV audio. Exact playback behaviour can still depend on the file and how the source is configured, so test your own materials rather than assuming a format label guarantees a clean result.
If the promo should repeat, enable the source’s Loop option. If it should play once, leave looping off and decide what should happen when it reaches the end. A black frame, a frozen last image or an abrupt silence can all look like a fault if the stream continues. A holding slide, a planned scene change or a deliberate return to the beginning is clearer than leaving the end behaviour untested.
Add the music file as a separate source when you want its level under independent control. Check the OBS audio mixer while the promo is playing. If the promo already contains a soundtrack and you intend to replace it, mute or remove that audio path deliberately. If the promo includes narration or sound effects that must remain, keep them and confirm that the added music does not obscure them.
For a pre-mixed workflow, do the balance in your editing app, export the completed promo, then add that rendered file as the OBS Media Source. Listen to the export from beginning to end before using it in the live scene. This catches errors that can be missed when checking only the editor timeline, such as a music track ending early or a last-second audio tail being cut off during export.
Balance music against the promo
There is no single fader position that works for every promo. A shop announcement recorded close to a microphone, a voiceover mixed in an editor and a video with no speech have different needs. Start with the music low enough that spoken words remain easy to follow, then listen to the actual OBS output rather than judging the mix from the fader alone.
In the separate-source workflow, play the loudest spoken section and adjust the music source while listening. Check the quiet moments as well: music that seems subtle under a voice can feel intrusive during a pause. If there is no narration, confirm that the music is not distorted or unexpectedly loud when a viewer turns up the device volume to hear the promo’s visuals or other audio cues.
Listen for doubled sound. If the original promo soundtrack has not been muted, adding the same or another track can produce a louder, muddier result. If the promo has its own narration and music, adding a second background track may make the result crowded even if neither source sounds loud alone. A clean mix is usually achieved by deciding which sounds are essential and lowering or removing the rest, not by adding more sources.
In the pre-mixed workflow, make adjustments in the editing project and export again when needed. Keep a copy of the project so that a later change does not depend on reconstructing the mix from a flattened video. If the promo is part of a broader channel loop, our guide to loudness normalisation for a YouTube music stream explains why consistency between items matters; it does not supply a universal level for this particular store promo.
YouTube’s encoder settings are separate from the creative mix. Its published guidance lists AAC or MP3 audio and recommends 128 kbps for stereo with a 44.1 kHz stereo sample rate in its advanced settings. Treat these as encoder-output guidance, not as a prescription for the music fader or a guarantee of good sound. Check the outgoing audio in the Live Control Room preview, because a correct setting cannot fix an unsuitable source or a poor balance.
Preview the whole intended duration
Do a complete rehearsal before the audience needs to see the promo. A short check can prove that a file starts, but it will not show whether the music ends before the video, whether a loop creates a gap, or whether OBS behaves as expected after the media source reaches its end. Test the full intended sequence, including the transition into the promo and whatever follows it.
Create or select the stream in YouTube Studio’s Live Control Room, connect OBS using the server URL and stream key, then inspect the preview before going live. YouTube recommends RTMPS for encoder ingestion. Treat the stream key like a password: use it only in the encoder and avoid showing it in screenshots or recordings. The official YouTube encoder help explains the encoder route and setup.
Watch the preview and listen to the programme output, not only the audio playing locally on the computer. Confirm that the image moves, the promo’s sound is present, the music is audible at the intended level and the stream does not have an obvious delay or unintended silence. If possible, verify the live output on the kind of device a customer is likely to use, such as a phone with its normal speaker volume. Desktop headphones can hide issues that are obvious on a small speaker.
For a repeating promo, observe at least one complete join between the end and the restart as part of the rehearsal. Check that the picture does not flash to black unexpectedly and that the soundtrack does not stop or jump in a distracting way. If the source does not restart correctly, fix the scene or export before relying on it overnight or during a busy trading period.
During the broadcast, keep an eye on Live Control Room notices and stream health, as YouTube advises. A preview is a useful check, not a promise that the stream will remain uninterrupted. For a longer-running channel, a rehearsal that includes the planned operating period and a way to notice a drop is more useful than starting the encoder and walking away immediately.
Plan for third-party matches and interruptions
YouTube scans live streams for third-party content. If the system detects a match, YouTube says the stream can be warned, temporarily interrupted or terminated. This is why rights checks and operational checks need to sit together: an operator may have permission for a track and still encounter an interruption if the rights holder’s Content ID arrangements do not recognise the channel as authorised.
A label on a file, a purchase receipt or a general claim that a track is licensed does not itself control YouTube’s matching system. Nor does calling the music “background” make unlicensed use acceptable. If a notice appears, read it, follow the current instructions in Studio and resolve the rights issue rather than repeatedly restarting the same flagged programme.
For a channel that uses licensed third-party music, YouTube’s guidance is explicit: “If you’ve licensed third-party content to use in your stream, ask the owner of the content to add your channel to their allowlist through Content ID.” See the current YouTube guidance on live-stream copyright issues. An allowlist is an action for the rights holder, not something YouTube automatically grants to a channel because the operator says they have a licence.
Keep a fallback scene or a version of the promo without the disputed track if your business has a permitted alternative. That does not remove the need to resolve the rights question, and it cannot guarantee that a replacement will avoid all platform notices. It does give you a practical way to stop broadcasting the questionable material while you check the issue. Do not assume that a stream ending cleanly means an archived version has no claims; review the recording and notices after the event too.
Verify any rights-holder allowlisting
If the supplier or rights holder says your channel must be allowlisted, ask them to confirm the exact YouTube channel and the relevant Content ID process. Provide the channel identity they request, not your stream key. A stream key grants control over where the encoder sends the broadcast and should not be shared as part of a rights conversation.
Ask for confirmation before the scheduled broadcast and retain the correspondence with the track’s licence details. Check whether the permission and allowlisting cover the particular track, the promotional context and the intended channel. Rights arrangements can differ between catalogues and tracks; a previous approval for another song, channel or campaign does not establish that this use is covered.
Then perform a test stream or rehearsal and inspect Studio for warnings. An allowlist request is not proof that the change has taken effect, and no test can promise the absence of a future match. If the channel receives a notice despite the confirmation, follow YouTube’s current process and contact the rights holder with the notice details. Do not rely on an informal assurance as a substitute for checking the platform’s status.
Keep the operational pieces easy to find: the approved promo file, the music licence or permission, any attribution text, rights-holder confirmation if applicable, and the intended stream scene. This makes it easier to distinguish a playback mistake from a rights issue. A pre-stream burn-in checklist can help you think through longer tests, though the actual rights decision still needs to be made for this music and this use.
Keep the playback running as planned
If the channel needs to run beyond a single scheduled promo, decide who or what will keep the encoder output going and how a failed playback will be noticed. A local OBS setup depends on the computer, the media file, the scene and the connection behaving as expected. That may be suitable when a person is present to monitor it; unattended operation deserves a more deliberate test and recovery plan.
Some operators want to avoid leaving their own computer responsible for repeating a prepared video. In that case, StreamNeo can remove that specific task by turning an uploaded video into a YouTube live stream that runs with the operator’s computer switched off. It does not decide whether a music track is cleared, replace the need to check YouTube notices, or make a rights-holder allowlisting decision on the channel’s behalf.
Choose based on the production you need, not only on whether a file can repeat. If you need to adjust music during a live session, keep the mix in separate OBS sources. If the promo is approved and its mix will not change, a pre-mixed file makes the playback setup simpler. In either case, the rights check, full-duration preview and response plan for a match remain part of the job.

FAQ
Can I use any song if it is quiet behind the promo?
No. The music still needs rights that cover the store promotion and YouTube live broadcast, even when it is mixed quietly. Check the track’s terms and any archive or territory limits before using it.
Should I add the music in OBS or in an editor?
Use separate OBS sources when you may need to change the music level independently during the broadcast. Pre-mix the audio and video when the final balance is settled and you prefer to test and play one completed file. In both cases, listen to the full result before sending it to viewers.
Does having a licence prevent YouTube from interrupting the stream?
No. YouTube scans live streams for third-party matches, and licensed material can still be interrupted if the channel has not been allowlisted by the rights holder where that is required. Ask the rights holder to follow YouTube’s Content ID allowlisting process and check Studio for notices.
Is a YouTube Audio Library track cleared for every store use?
YouTube says its Audio Library contains music it knows to be copyright-safe on YouTube, but you should check each track’s licence and attribution requirement. If the store will use the music outside YouTube or in a wider commercial campaign, confirm that the specific permission covers those uses too.
