Starvynth or Yaniv can probably give a better explanation.

As for multiple profiles, I'm not 100% on this, but there's a difference between renaming a band an keeping the entire catalog like Electric Callboy, or leaving the catalog and starting to release under a new name like Rhino

Rhapsody's profile for example links to Rhapsody of Fire in its aka field

they are usually linked in aka

It's confusing to see multi profiles of a same band, and not everyone is aware of it. We can add these in a different section of a.k.a to let folks aware about it.

I personally wouldn't be able to stand the Devin Townsend pages being split

Yeah it's weird. Especially since they're literally the same band but were just forced to change name lol
