The artist's share of income from record sales and radio play has been next to nothing throughout the history of the record industry. Any experienced artist will tell you the real money comes from live shows and merch (which can still be pressed discs). This is why file-sharing only hurts the labels, not the artists. The artists actually get more exposure without losing much royalty income from the illegal downloads, which actually help promote the band and draw bigger live crowds to gigs where they can actually make some money.
