The only relevant apps I've run into have been by Reverbnation and BandPage, of which at least RN supplies more than just a player. I don't like either, so I prefer to make my own when necessary. (Both apps seem to get the job done, I just don't like them visually and dislike some of the clutter and how the functionalities have been implemented.)
When choosing your apps, keep in mind that you can only have two of them visible all the time - the rest require an extra click.
If I were on the lookout for FB apps, I'd try to find a music player and an app for gig schedules or promotions. A shop might come in after that if necessary. Other custom content is just extra.
Edit: Bandcamp has their player app as well. Silly me, I forgot.
