I don't usually run with music because I am with a group when I run outdoors.  If I am by myself, I do prefer the solitude to the music.  However, I would not survive running on the treadmill without my ipod.  I like an eclectic mix when I'm running, but the more upbeat songs are more motivating for me...

Jeffbc, you have a great playlist!

In the interest of brevity, I'll just summarize my playlist by saying aggresive music like hard rock/punk is what drives me to run faster. Two songs in particular that give me a little extra boost:

"How Fast Can You Run" by Rocco de Luca (how ironic!)

"Far Behind" by Social Distortion

"Scarlet Begonias - Fire On The Mountain" - Grateful Dead from the Barton Hall show, 5/8/77.  25+ minutes of Jerry and the boys jamming away - works out to an 8:40 pace - makes Miles 7-10 disappear in a Half.  I count on this one to get me through the Wall every time.  

I use September by Earth, Wind and Fire as my power song!  It really gets me pumped on those long runs and races!

I listen to my iPod on the treadmill and on the local 2 mile loop. It's the only way I can run.

Best for me:

• Don't Tell Me by Madonna

• Blood Makes Noise by Suzanne Vega (this is my #1 running song, perfect pace, perfect rhythm)

• Slim Shady and Lose Yourself by Eminem

• Let's Get It Started & Pump It by the BEP

• We Care A Lot - don't remember who it's by, but I downloaded it after watching "Dirty Jobs" and remembering how much I love that song

• Opening Credits Theme from Men in Black by Danny Elfman (no, not Will Smith's song, this is just the instrumental music). For that matter, LOTS of stuff by Danny Elfman is fun to run to.

• Babylon 5 theme songs, great for a quick short sprint

• Theme from Mission Impossible

• One of the James Bond themes by Moby

• Cantaloop (forget who this song is by)

• Devil Went Down to Georgia by the CDB

• Just a Ride by Jem

Woah!!  A lot of great song suggestions!!

I've been working on my new running mix - here is what I have so far (although I'm going to add a lot of the songs suggested in this thread)

Paul Oakenfold - Ready Steady GoDirty Vegas - Days Go ByZombie Nation - Kernkraft 400

Well I seem to be the opposite of "old school" im more into the new age type of stuff which would be something along the lines of hardcore/punk and such. Im not too sure why, but it seems to really pump me up and get me into the moment. I find that in slower songs i get off topic and end up getting to much into what i am doing. Honestly im not one to really train with music yet when I do its more to get me motivated. Some of the songs would be Chiodos, A Skylit Drive, At the Throne of Judgement, and those types of music; NOTE: if you are not for hardcore do not even look them up. This music is more the kind of stuff that gets anger out and gets you extremely motivated (well, me at least).

Reguards.
