What's on your exercise music playlist?

So, I'm starting to use my exercise bike prior to WLS.  I have to have fast-paced music to keep me on any exercise machine.  I get lost in the music and keep my motivation going when I'm listening to some rockin' music.  My ipod is getting a little dated right now.  I haven't gotten any new music in a while and I wanted to know what some other people were listening to when they exercise.  Give me some suggestions please!

Note:  Just because I'm black DOES NOT mean that I only want hip hop music.  lol.  I have a very eclectic taste in music.  I'm all over the map.  I like pop, rap, hip hop, country, blue grass, rock, metal, alternative, gospel, latin, orchestra. 

Seriously was going to ask the very same question. Right now I'm lovin Dynamite by Taio Cruz & Savior by Rise Against. I love music and it seems to help pass the time and get my mind off of the fact that I'm sweating and just keep pushing thru the pain. Anything you wanna share music wise is welcomed too.

I posted this same thing on the main board and got a lot of great responses so check that out.  As for myself.  I'm almost embarassed to make any suggestions...lol  My ipod is so outdated...most of the stuff I have is old.  Just a few of my faves. 

A lot of Missy Elliot (We run this, pom pom, etc.)
A lot of Black Eyed Peas ( Pump it, Boom boom pow, etc)
Creed ( Torn, What's this life for, etc)
Kelly Clarkson (My life would suck)
Evanescence (Going under, bring me to life)
Pink ( So what)
Lady gaga (Telephone)

Great suggestions by the way.  I'm making a list of songs to add and both of those are going on my list.
