There does not appear to be a “Repeat album” option in the iOS 7 music player. A bit annoying.
Additionally, I’ve noticed some volume issues in playlists, where songs will suddenly get louder or quieter within the first few seconds. Perhaps something amiss with “Sound Check”?
In any case, there is apparently an update to iOS 7.0.2 that mainly corrects a security problem … perhaps these will be addressed, too?
UPDATE: Answered my own question, sort of. Please see this newer post.
