Hi there, I am new here, but I've been a fan of both this forum and your work as "The iTunes Guy" over at MacWorld for a while. I am rebuilding my entire iTunes, and am encountering a problem involving 'sort artist' in the process. For example, John Legend is displayed in the artist column browser as "John Legend & The Roots". Out of the five Legend-songs, the first four have "John Legend" as the (1.) artist, (2.) album artist, (3.) sort artist and (4.) sort album artist. The fifth song, "Wake Up Everybody" has the following data. - artist: "John Legend & The Roots feat. Common and Melanie Fiona" - album artist: "John Legend & The Roots" - sort artist: "John Legend" - sort album artist: "John Legend" The reason for this is that I want to avoid having both "John Legend" and "John Legend & The Roots" show up in the artist column browser. The good news is that it sorts the songs together now, however, for some reason it seems to have changed the sort album artist to "John Legend & The Roots" for all five songs. I can't for the life of me figure out where I went wrong. Does anyone know how to fix this? Thanks in advance!
