I believe you can have 2 or more accounts. I need to figure this out too because I HATE having Justin Bieber, High School Musical, Miley Cyrus and Camp Rock 1&2 in my library collection. I really should have thought through giving my teen DD an iPod! I do know you can have your own playlists, then you can pick and choose which ones you want on which iPods
Also, I HATE those damn earbuds with a burning and firey passion! They never stay in my ear. I use BOSE buds. They are pricey but they sound wonderful!
I'm sure you will find the answer on these forums!
