There was a scam a while back where computer manufacturers would buy one copy of Windows and install it on every machine they sold. People thought they were getting a legal copy of Windows, but they weren't. Some manufacturers were even loading up with Office, Photoshop, etc., so that the value of the pirated software was greater than that of the computer.
I don't like RIAA, but they've got a point, here.
They have a general point, but still miss the fact that copyrights aren't absolute. I looked up on how they interpret the Doctrine of First Sale, and it sucks. The law allows you to resell or destroy a "particular copy" of a copyrighted work. The RIAA makes the case that ripping your CDs to an iPod and selling the iPod and the music (let's say your oriringal CDs were destroyed) is not that "particular copy," which resided on the CD that got destroyed.
As usual, they miss the spirit of the law. You paid for it, you can resell it, just don't resell it more than once. But the secondary market hurts their pocketbook, so they'd like to get rid of it.
Copyright was only intended for useful arts, things that benefit society.
Britney Spears doesn't count, so no, it isn't copyright infringement.
This of course assumes you don't delete your original.. something the RIAA has no way of knowing. Again the RIAA is full of fecal material.
