Throughout my experience with Spotify I found many problems, some being:
A band having two profiles (Razor)
Bands with no albums at all, only compilations or singles, and sometimes Spotify recommends the missing albums but they cannot be played (S.O.D., Bulldozer, Grim Reaper, etc etc)
Bands get mixed up and end up in other bands profiles, but that usually is quickly fixed, thankfully.
I know this problems can be fixed! Spotify already fixed the Nailbomb profile, that didn't have their own album their, but separately. Now I'm counting with you and Spotify to fix this problems, and then we can start thinking about adding more bands.
