Song Tapper, via SFU

I randomly dropped by the old alma mater's website, and ran across this story:

The simple, rhythmic bopping of a finger has led a trio of SFU computing science students to solve a musical dilemma - how to name that unknown tune.

They've created Song Tapper, which can be found at www.songtapper.com. The website has been designed to enable users to identify songs by tapping the melody on their spacebars. The site has grown from a few hundred songs to well over 11,000 tunes and attracts as many as 10,000 hits a day.

I tried it out successfully on the following songs:

I Wanna Rock and Roll All Night
Instanbul was Constantinople
Yesterday
Billy Jean
Closer
Super Mario theme song
Creep

I tried out some songs that don't seem to be in the database, but the system does pretty well with the ones it knows. Way cool.
