Edit: Appears to be orphaned. Sent 3 emails over 5 weeks....no response to problem. No access to music, only podcasts.
After IOS 8.4, it seems that Apple has killed access to albums, artists, genre, etc. playlist still work....but this app is essentially dead if this is not fixed. Before this, the app was great.
