All the songs named SOS by different artists?
Actually, Demi Lovato doesn't write all of her songs. On her first album, most songs were consisted of song written by herself and the Jonas Brothers, with only one song written by herself. It mostly had songs that were written by a team not including her. On her second album, she teamed up with many different artists from Nick Jonas to John Mayer.
Can you view all of the artists and all of their songs on one page with the new itunes like how you could with the older one. i have itunes 8?
If your problem is that your album is separated and says that each featuring artist comes under a different album, you should just highlight all of the songs in the album (CTRL+click multiple songs) then right click on any highlighted song and choose "Get Info" then under the heading "Album Artist" type the name of the artists and all the songs will stay together. Hope this helped
