Do you have rhythm?

From the Metro, the Song Tapper alllows you to tap in the rhythm of a song and then tries to match it to its database to tell you the title. This is targeted at everyone who has a song going round and round in their head and they’re trying to find the title. Unfortunately, on my few attempts it did not match any of my songs. However, that may say more about my complete inability to tap out a rhythm than a failure of the system.
