I was searching for something else when I came across this site. You use your spacebar to tap the tune that you have in your head and the site will come up with several songs that may be the one you are looking for. You can even hear what it was you tapped. You will hear it played back like a piano. :lol: The song I tapped did not come up in the list, but I was stunned at the choices it gave me. Very interesting...

That sounds pretty cool, I'll have to try it out.
