Very much depends on my mood and when I run. If it's very early in the morning, around dawn or so, I listen to just some classical music, or just a simple piano. It's very relaxing, and strangely enough when you are out and running, you can still be mentally relaxed. In a trance kinda. Just you and the road.
However, if I am running at any other time I usually listen to some rather fast tempo metal music or techno. But it really comes down to what you enjoy listening to, I feel. If you fucking love classical music, then listen to that. Don't need any specifics

But, here is my current two lists, anyway! Enjoy.
Also, all of those songs can be found on youtube, then you can just use a youtube2mp3 site to convert and download them to your computor
