I'll give you three:
-Hedge
That Prodigy video has a nice ending...
Here are a few cool ones. Not so much pre-gym motivation, just worthwhile.
- The Perfect Drug.
Makes me think of working out, being at the gym - the pump. Vanity is the perfect drug. Mother natures opiate.
This video & song are also pretty neat. I find these NIN tracks make just about any video that much better.
<-- amazing... was displayed on a huge screen at their shows on tour
<-- interesting fact based Mars rover animation
<-- this song is badass. You may recognize it from "300" trailers.
Here is some of the new stuff.

Be looking out for the new album. Trent is basically giving the whole thing away free online @ perfect 320lkbps mp3 in a A.R.G. consisting of hidden sites and messages for his true fans. Essentially saying, "here is my work, support me if you like it." Pretty rare these days. Especially since its
guaranteed to sell extremely well.
