Today's website of the day is songtapper.com a website that names that tune by tapping.
Tap the rhythm of a song using your space bar and Songtapper will endeavour to find the song title, artist and the lyrics.
There's nothing more annoying than travelling to work of a morning with a song on the brain and not knowing what it is.
Here's a simple (and silent) solution to help you out when you get to your desk.
With a current database of over 16,000 songs, you may find it's as much fun trying to find one that it doesn't know. Or maybe that's just me.
If you have a website that you want to tell us about email us via the feedback form.
