Math of Christmas Carols

BoingBoing reader Ben Dalton says,

"Brian Whitman, maker of eigenradio (which "plays only the most important frequencies, only the beats with the highest entropy") has released a happy holiday album automatically derived from the principal components of 'all christmas music'. Description, from his site: 'This season, as a present to friends worldwide, our system listened to as much Christmas music as it could handle. When it was done it synthesized these sixteen new timeless classics.' Great stuff."
