Midomi

Ever wondered about the name of a song but unable to find it out? You don't know of the name or artiste and your friends haven't heard of it either.

Midomi aims to help you.

Hum the tune of the song and the site will use tone and pattern recognition software to try and match it to the correct song.

The system is far from perfect. It relies on user-submitted song snippets-it doesn't actually try to match your humming to the actual song. It's recognition software is also quite inaccurate to allow room for error on your part when humming.

Other than that, it's a regular song site.

Hopefully, in future they design the required software to match your humming to the actual song itself.
