Tom Waits - Underground (Chopshop Mix) 

A mashup/mix of Tom Waits' Underground and John Powell's Chopshop (itself derivative of Underground, created for the movie Robots). I found both versions to be, in their own ways, unsatisfactory, and while I'll admit I'm not the best at this sort of thing, I think I did well enough.
This is the third upload of this dang thing because the audio wasn't loud enough the last two times.
