Are you looking for a song but only know some of the notes to it and the title simply escapes you?  Then Midomi might just be for you.  Just sing, hum, or whistle into your microphone and let Midomi find your music for you.  It's not perfect, but it is a new revolutionary way to find that lost tune you don't know the title of.  It requires that scripts are turned on in your browser, so be careful.
