Seriously, this is another example of patent over-reaching. Software patents should be for really creative ideas, not merely something that is as obvious as downloading a music file from one computer to another.
Although, at the time, it may not have *seemed* so obvious...
That said, this *might* cripple Microsoft's Zune further. Not that it needs help to be crippled.
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."
