How to add background music to a post
I kept picking the same three tracks and hunting for them every single time, in a list that reset itself the moment I switched project. The music library sits inside Create Post. Pick a track, set its volume against the original audio, and star the ones you keep coming back to.

Good to know
Favourites are saved per user and per project, so each project keeps its own shortlist. Music-only jobs (no crop, no overlays, no captions) skip the heavy re-encode entirely and just mux the audio. That is why adding music alone is fast even on a 100MB file. Tracks are loudness-normalised so one is not suddenly three times louder than the next. If a post is parked and resumed later, the music is reloaded from storage first, so a resumed render never silently drops the track.
Can I upload my own track?
Yes, through the library. Make sure you have the rights for the platforms you publish to.
Does the music survive the platform variants?
Yes. The audio master is produced once per submit and reused by every platform version, so all of them sound identical.
