Is there a way to export the entire contents of an iTunes library, including playlists, album artwork, comments, and song ratings, to another computer? In other words I want to make a completely identical copy of my library to go to this other mac. I tried this once simply by transfering the songs and all the playlists and all that happened was that I had the songs with all of the ratings lost and the playlists were empty (since iTunes playlists work off of the location of the songs on the hard drive). Perhaps there's a program to do this?
