I heard about this website where you can buy previously owned legal digital downloads. The basic idea is it's like a used CD store where you upload the song you legally purchased from ichunes. The website then wipes it from your computer and you can still stream the song from their site until someone buys it, at which point you get some money and lose control of the song.
What does everyone think of this? Ignore the debate of if it is possible to just copy the song to a USB stick or ipod and still have it.
Good idea? Bad idea? Blatant copyright infringement?
