“Music Discovery” channels are not covered under a Musicbed subscription or single use license. Musicbed provides sync licensing, which is music synchronized to video with the purpose of sound-tracking the visual creative content! Music Discovery channels’ sole purpose is to share music and/or playlists (not to create original video content).
One way to think about this is in terms of who’s “center stage” and who’s in the “background.” With a sync licensing use, the song is always in the background of the video, the star of the show (ex: commercial jingle, film soundtrack)! A Music Discovery channel would include video as a backdrop to the song taking center stage. An example of this might include a static shot of someone studying in a cozy window (cute, but not covered by a sync license!)
Music Discovery channels require a Performance License, since they are more closely related with a Public Performance.
