I'm sure some of you are already familiar with this, but Microsoft has a new research project called Songsmith:
Songsmith generates musical accompaniment to match a singer’s voice. Just choose a musical style, sing into your PC’s microphone, and Songsmith will create backing music for you.
Except that isn't what people are doing with it, at least not some of them. They are isolating classic song vocal tracks and piping them through Songsmith instead.
And it is
creepy:
It started out with a little
David Lee Roth, which is fairly hideous.
And then there is the
Police's Roxanne re-incarnated as a Caribbean hit.
There are plenty more, like Oasis'
Wonderwall, but I won't bore you. You can dig into it if you find it interesting, or, hey, go
sing a song yourself.
Update: I think
Long Train Runnin by the Doobie Bros is the best so far.
