I have 2 laptops. My songs/appz are on one laptop but I want to at least be able to manage the songs, playlists, etc on my other laptop. I log onto itunes on my 2nd laptop and itunes want to backup my files. What is going on? Is it copying the songs, playlists, appz, etc to my other laptop? I prefer it does not do that. I just want to manage playlists and song info on my touch on it. Is that possible?
