Can you have two iPods on one computer, but have there own music?
Yes. You can have one library and share music, apps, pics, and such or you can set up two accounts on the same computer (but why would you pay for stuff twice?)
Yes.Goto the music tab on iTunes after connecting ur iPod and find an option like selected artists only or sumthin like that I forgot what it was
Yes but why when each one holds thousands and thousands of songs ? Do you have that many songs ?
