How does iTunes decide how to sort music in the iTunes music folder? Sometimes it sorts by the performer, sometimes by the album title. How can I get it to be consistent?I burn a lot of CDs, but don't leave them in iTunes unless I put them on my iPod. So I "delete" them, but keep the files, then often go searching through the folder to find which ones to add back on. But they are all a mess, organized in an irrational way it seems.How can I fix this?Walter Ramsey
