So, suppose that you link the same artist twice to the same album, but in each link, you give that artist a different alias. This works perfectly fine in the album display page, showing each of the aliases separately. However, when you view that artist's profile, only one of the aliases actually shows up.
Before you think I'm just doing something colossally stupid just to break the system,
Koichi Namiki is credited with two different aliases on
GALAXY FORCE II & Thunder Blade ORIGINAL SOUND TRACK. I think this might be the only album on the planet where someone is credited twice with different aliases.
