Query-by-HUMMING Song Database!!

AWESOME!!

IIT-B Digital Audio Processing Lab (DAPLab) has a song database that is queried by HUMMING a tune! A god-send for music enthusiasts with a bad memory, like myself.

I wonder how this could be extended...? What if you could just say a few words that appear in a song you somewhat remember, without a tune, and it could retreive all songs that have those words in it? The database should not have to contain lyrics to all songs though. When adding a song into the database, you just upload the audio. The system 'listens' to it and extracts a few key words and phrases, and when it's queried, returns those matching songs. Wouldn't that be cool?

Anyway, I think what they've done up till now is cool enough.
