ok so im not sure how to explain what i need help with but here goes... my brother got an ipod for christmas and i already own an ipod. on my itunes i have a bunch of music and playlists that he dosent want on his. is there a way to have 2 separate itunes library's so that when i sync his i dont have to uncheck half of the songs and recheck for when im syncing mine?
if this does not make sense let me know and ill try to rephrase it.
thanks

Probably the simplest way is to make separate user accounts on the PC for you and your brother and install itunes in both accounts.
