The Beatles' "Eleanor Rigby" and Lipps, Inc.'s "Funkytown" were pretty, and I didn't expect Britney Spears' "Oops, I Did It Again" to be so frenetic and thin, but I think my fave may have been Charlie Parker's "Donna Lee." All you cats out there, jazz is beautiful math. Dig it: The Shape of Song.
My favorite part of the site is, dangit, the part the I understand least. One can follow along the note structure of the song to see how it graphs.
