See, here's the deal. I can put 5,000 or so songs on my iRiver, so that's about $5,000 worth of music, should I ever fill it up. Now, were my $300 iRiver to cease functioning, or be lost, or dropped in a vat of oil, I would need to purchase all those songs again, unless I can copy my purchased songs. I have gone through three MP3 players already. Certainly, I am not prepared to repurchase the digital files each time. This is simple common sense. And the Institute for Public Policy Research (IPPR) agrees.
