There's this thing called Songsmith. It's software that automatically generates music to go along with a vocal track. "Just choose a musical style," says Microsoft, "sing into your PC's microphone, and Songsmith will create backing music for you." That's right, create backing music for you. (I wonder if Sarah Records is one of the styles they offer. Anyway.) If you don't believe me, check out the Songsmith site. I've heard the intro video is funny, but I couldn't get it to play. I know what you're thinking.
"What if I don't know how to write music?"
No worries: "Songsmith is for you. Get your first taste of songwriting just by singing into a microphone, then explore different styles and arrangements, even if you don't know the first thing about music theory."
Attention all Nashville bands: Please do this with vocal tracks from your band. Immediately. I sincerely doubt that your song will be even one quarter as awesome as this Songsmithed version of David Lee Roth singing "Runnin' With the Devil," which sounds more or less like Casiotone for the Painfully High Jump-Kicks.
Of course, I'd love it if you proved me wrong.
