Here's the problem. My ipod is full and I got bored with my albums. I'd like to exchange some music, because I have a better selection in my iTunes that I'd like to be in my ipod. How can this be done?
RJS is correct. Learn how to use playlists and my favorite... the smart playlist. You have to set up iTunes so you get control of what goes on your iPod. Right now iTunes just puts songs on there until your iPod is full. You have to unselect that checkmark and set it up to only load your playlists onto your iTunes. You can create playlists and drag the songs you want into your playlists or you can use smartplaylists. If you use smart playlists you can quickly set it up so each smart playlist = 1 album... or make each playlist have all the songs from one artist. Plus there are may other ways to use the smart playlist.
Yes, what I do is create a smart playlist that includes any song that has a 3 star rating or higher. Then, as I rate songs, it adds them to the playlist. That playlist is synced to my iPod.
