I just got an iPod, and when I connected it to my Mac, I allowed it to automatically sync. I have not created any playlists in iTunes, so the default ones were "90s Music", etc. I noticed that now my iPod Shuffle has all of the default playlists, the Music folder from my library, and the Purchased folder. I went ahead and deleted the default playlists from iTunes because I don't use playlists, and it was taken off the iPod. But both "Music" and "Purchased" folders are still on the iPod with the same songs (I have not ripped anything into iTunes). Is there any need for these two folders? Should I delete one or the other? How come the Music folder in the library will not let me drag songs where I want them?
