Re-install iTunes?
Playlists and whatnot are contained in the iTunes folder, not the app. Just move the app to the trash and re-install. You won't lose your prefs or playlists.
I installed Lion and the new Itunes update today. This is what my Itunes looks like now :/
I desperately want it to go back to the default and did try and delete Itunes but it wouldnt let me.
HELP!!
