Epidemic Sound

Epidemic Sound is a subscription music library where the licence covers commercial use across platforms in one arrangement.

That single-licence model is the practical value: music rights for video are otherwise fragmented — a track cleared for YouTube may not be cleared for advertising or for a client's project, and getting that wrong results in claims or takedowns.

The licence is tied to the subscription, so understanding what happens to already-published videos if you cancel is worth checking before building a catalogue on it.
