I've Got Rhythm?

Today I amused myself with Song Tapper. Using only your space bar you can tap out the rhythm of a song and it will guess what you are tapping. Of course, I have no rhythm and was horrible at it. It only got one of my attempts (Like a Virgin by Madonna) but it was still a fun way to pass the time. My favorite part is listening to the tap play back. No wonder they can't guess any of mine, they all sound like a cat ran across a piano and fell asleep on some of the keys.
