Apple patents workout music matching

It seems that Apple may have plans for incorporating the iPod into your workout other than just the integration with Nike sneakers, as a newly released patent shows that the company has invented a method of adjusting the pace and style of music playback while you exercise. Incorporated into a model called the iPod Sport, perhaps, this technology would use an accelerometer to gauge the pace of a person's workout, and encourage them to "take it to the max" by either increasing the tempo of a particular song (though hopefully not to the point where all your tunes sound like Alvin and the Chipmunks) or automatically changing to a faster-paced track. This is all well and good, but how about throwing in some Bluetooth while you're at it, cause the wire dangling from that runner's head in the illustration has got to go.
