Title: Air
Artist: Anna\\Betty\\Chelly\\Diane
Title: Break
Artist: Sphere\\Anna\\Betty\\Chelly\\Diane
Air is sung by 4 people. Break is sung by 4 people under the name 'Sphere'. Taking a look at the artist column within the Column Browser, Anna has two separate entries.

This problem becomes much more rampant when dealing with artist singing solo and within a group. The position of the artist's name seems to matter a great deal when sorting by artist. Is there anyway to merge the artist together?
