If you've seen the new Audi commercial, then you've already heard a cool mash-up of the David Bowie classic "Rebel, Rebel" and Bowie's brand new rocker "Never Grow Old" from his new REALITY album.

What is a mash-up, you ask?

A mash-up is a song created from parts of other songs. Mix and mash two or more songs together to create something new and you will have a mash-up.

The folks at DavidBowie.com want you to mash-up any track(s) from David Bowie's REALITY CD and any other of your favorite Bowie tracks. Mix, match, mash-up and make something new, -- do it well enough to rock Bowie's world, and you might win an Audi TT coupe!
