I have a question on how to change the way iTunes sorts music by artist (if it's possible). I have a rather extensive jazz collection on iTunes, and the thing about jazz music is that you very often see artists performing with their peers. So my collection, when sorted by artist, as I prefer to look for things, is rather jumbled. I'll have a "Dizzy Gillespie" section, and then about 7 or 8 "Dizzy Gillespie & so-and-so" sections. Is there a way to have iTunes catalogue a tune under two different artists without duplicating the song? That way, instead of having a gazillion "Artist A featuring Artist B" sections, I could look up Artist A and see the song, as well as seeing the same song under Artist B. Thanks!
