Well, I'm not exactly sure what I'd do because that is one way-out-there hypothetical question, but I'm pretty sure that by the end of the day, a lot of people would be thinking that Vanessa had lost her marbles. I would probably lock myself in a big studio (like the one where the MTV duet was filmed) and play everything I know for hours and hours, stopping about every fifteen minutes to spin, twirl, and flip around the room like a drunken lunatic and yell and scream and then go back to playing "my" music.
But in truth, back to my original answer, I don't really know.
