I am T-Pain.

Okay, obviously, I'm not. But I did play with the much-talked-about "I am T-Pain" iPhone app for like two hours with Brooke on Wednesday night and did not want to put it down!

Basically it just takes your voice and auto-tunes it. Auto-tune was developed originally to correct the vocals of people like Ashlee Simpson who can't really sing but are singers anyway. T-Pain is famous because he was one of the first people (alongside Cher, of course – "Believe," anyone?) to use auto-tune to distort voices and make them kind of mechanical and able to hit waaay too many notes.

If you have not yet experienced the wonders of auto-tune, I bring you a couple of videos.

(Pardon a little language in this one.)

Even if you don't like Kanye, just wait out the first 40 seconds or so and see Charlie and Harry get auto-tuned!

The problem is that I keep getting these auto-tuned songs stuck in my head. For the record, it is very hard to hit like twelve notes that span three octaves in one syllable. (Not that I normally hit all the notes.)
