Download of the Day #29

Ever have that song in your head but don't know the name of it. Well, this program comes close to identifying it. If the song in question is on the radio or you have access to it, Tunatic can tag it for you.
Ever thought ‘what is this song?’ Let Tunatic hear it and you will get the artist's name and the song's title within seconds. Tunatic is the very first song search engine based on sound for your computer. All you need is a microphone and Internet access.
I don't know how practical it really is, but sounds like a good concept. And hey, works with both Windows and Macs.
