My favorite song to run/workout to is...

I forgot about Disturbed! Down With the Sickness would be great to run to!

It is. Since I now associate that song with Dawn of the Dead, when it comes on, I pretend I'm running from zombies.

For pure motivation, I go with this: http://www.youtube.com/watch?v=oAlztMvvNkk If you happen to be a fan of the show, you know that the badassery that accompanies this makes it amazingly motivational.

When I want something that's upbeat and good for kicking up the RPMs on the elliptical, I go more for techno tracks:

Deadmau5 - I Remember ( I zone out and keep a pretty good pace when this comes on)
Coldplay - Paradise (Motivates me to increase pace when I start to get a bit tired)
30 seconds to Mars - Battle of One (The last sprint(s) are usually to this song. *kitten* is intense!)
