Facebook has made it very clear that they do not want users attempting to replicate or mimic a streaming music listening experience in their platform (ie: They are not a streaming music store like Spotify, Apple Music, YouTube Music, etc.).
For example, a user or artist that uploads a still image as a video with the music playing behind it would be prohibited. This type of usage is not allowed even by artists posting stories with their own songs.
Additional restrictions related to eligibility requirements can be found here.
