This person better hope they never have any computer viruses, or any problems with their Ipod, unless they want to have to pay for the same music over and over.

But he has his music in at least two places, the iPod and his computer. And he can backup any music. This is far better than the pre-CD burning days, where you were toast if you scratched your CD.
