I am an iTunes user, well soon to be ex-iTunes user as I love spotify so much now.
The only real preference to iTunes I have right now is the more customizable "view" of tracks, playlists, albums.
Now we have Track / Artist / Time / Album / Added / User - and you can't move them, or remove them, just resize right now.
iTunes has like 50 different options here.
Mainly though you can add or remove as many as you like.
But MOST of all the one I like best is the "played" which adds a column showing how many times you have played said track.
As I listen to lots of podcasts, audiobooks, and such this column is very useful so I can easily find out what I have or haven't listened to yet, especially in long lists of chapters etc.
Sorry if it's been suggested!
