An interesting post on Amazon’s MP3 store. Woven through this is the notion that the invisible hand of the market once again let itself be felt: record labels aren’t dropping DRM because it’s the “right” thing to do, or because consumers complained, rather because they needed competition in the song delivery marketplace dominated by iPods (as listening devices) which either allow Fairpaly or unlocked songs. So if they want to get music onto these devices, and get more than the $0.70/song that Apple is willing to pay them, they need to sell without DRM.
