Hi @stevecummins78, welcome to the Sonos Community!

The implementation of Bandcamp on Sonos doesn’t have the ability to play from your playlists, only from your collection. 

I’d suggest you speak with Bandcamp on adding this feature to Sonos, as each music service is responsible for what content they provide to the Sonos app, which playlists are not a part of.

I hope this helps!
