I just found this, midomi, which looks to be way cool. At least, it would be if I had a microphone hooked into my computer. If someone out there does, I’d love to know how well this search engine works. Oh, it’s designed to help you find that song that you’ve got stuck in your head, but can’t remember the name of. Apparently, you can hum, whistle, or sing the tune and it will find the song.
