One of the worst and most surprising problems that people encounter with the iPod, iPhone, and iPod Touch is that when you plug into another iTunes account you do not have free range to download that music. It seems like a perfect set up, where you would be able to take around your portable storage device for media and capture up all the music you want from your friends. Unfortunately, Apple has tried to protect the music industry and their own iTunes interest and have allowed you to properly sync only to one iTunes account. That does not mean you can't take some music from somewhere else. There is a very quick and easy way to take the music you want from the computer you want whenever you want.
