I think the key here is, as "hard" copies of music (CD's, etc) are downplayed by the producers, we'll buy our tune for 99 cents off of iTunes, and, at least in theory, repurchase the same tune 5 to 10 times over because of various hard drive crashes, and software modifications, so that the labels make insane profits off of each tune. Remember, we can't copy, so copying them from HD to HD or backing them up is expressly forbidden.
Screw 'em. If I can't download "Ring of Fire" for free, I'll just learn to PLAY it on my brand new Ibanez (see my related article "I Have an Ibanez", for more details). They can't sue for royalties on THAT!
(or did I, err...give 'em an idea?)
