Each iTunes library can only have one iTunes account. You can start a new iTunes library by quitting iTunes and then holding Option and opening iTunes back up. You won’t have any of the songs from the other library though, they are completely separate libraries. You can’t have two different iTunes accounts hooked up to one iTunes library as of now.
Q&A: My husband just ordered and older iPhone for the first time. Right now we don’t use the internet at home (except on my phone), just at work and I only have one computer at my disposal for the time being. If I log out of iTunes and he logs in with his account can he sync up on my computer or do you have to use two different computers?
