I'm sure you have seen the recent news story about the guy from Australia who traveled 16,000 miles across the USA without using a drop of fossil fuel.. I think it'd be cool to do a spoof that where someone drives 16,000 miles without ever hearing the same song twice or changing a single CD.

My buddy wrote all of the Roxio commercials that were on TV, I should email him and tell him to pitch it to Rio. lol
