OK, I really need some help here, and I'm not very technical. can someone give me step by step help on this? that is, assuming I can do what I plan on. my daughter has about 350 songs on her nano that are not on my hard drive. she'd like some of the music I've got on my hard drive downlaoded to her iPod. is there a way to download from my computer to her nano without deleting what's already there? and is there a way to upload those 350 songs from her iPod to iTunes?
