I just got my 5G iPod, which I am happy with. The only problem: My brother and sister have iPods, too. Unfortuantly, my sister also likes N'Sync and Britany Spears. When I go to update my iPod, I check the songs off of the Library so they don't get transferred to my iPod, but they still do. I feel shamed that N'Sync has to be on my iPod, taking up valuable space. Is there a way that the songs aren't transferred to my iPod, but my sister can keep it on hers?
