Might have something to do with the music industry trying to force Apple into the new agreement by letting Amazon having better pricing and DRM free.
That's correct, the industry fears Apple's growing dominance in music retailing. They began playing hardball some time ago. Apple makes a few cents per track -- the pricing on the iTMS is a reflection of the industry's wholesale pricing. That's why a CD costs what it does; that's why digital downloads cost what they do. But if there's one thing we've learned, it's that this simple fact can be repeated over and over, but some will never believe it.
