Funny that so few Apple fan-boys are pointing out the obvious in praising Apple's DRM-free deal with EMI. The latter company is an also-ran in physical and digital music, with something like 9.4% share. Dropping DRM and thereby increasing piracy is, in those terms, another way of saying that also-ran EMI is slashing prices (to zero at the margin) to buy market share.
One user ("Rob") points out in the comments, though, that this move is unlikely to increase piracy... EMI's entire catalog is already available on P2P networks at 256 kbps or higher.
Just something to think about.
