It should also be mentioned that this patent gives Apple a big bludgeon to use against the music companies that will try to screw it out of its' pricing model, as well as competing music stores.
"If you don't sell with us, you won't sell with anyone, because WE own the patent."
Patent wars actually being used to help the consumer? That'll be a new experience. We know there's been immense pressure by the RIAA to jack up iTunes prices for years. The RIAA is backing Zune because the entire Zune model is centered around bringing income to the RIAA instead of giving the consumer what he wants. Patents as a way to stave off the RIAA's greed? I almost like it.
