Song Tapper

Ever have a song stuck in your head, but you can’t quite name the tune? A new tool developed by three students at Simon Fraser University, in British Columbia, may be able to help. The Song Tapper allows users to tap a beat on the space bar and get a list of possible titles in response. The site evolved from a project last year for an artificial-intelligence class and now gets as many as 10,000 hits a day.
