The music industry should now be free to support artists that are signed for individual song contracts rather than whole album deals. The slow death of the album format (masterpieces like American Idiot notwithstanding) is no secret, and since it's so easy to sell individual tracks over iTunes now, the market is ripe. I'd be surprised if some of the one-hit wonders we've seen lately were not signed on a single-song contract.

PS - Of course, artists don't need music labels to sell their tracks directly.
PPS - That's the beauty of the internet.
