L.S.
All of these are great! I just got a new iPod and am putting some good running songs on there, too. I like Machinehead by Bush, What a Feeling (FLashdance) by Irene Cara, The Way I Are by Timbaland, Boys of Summer by Don Henley.
I also have a couple songs on mine that I didn't originally have in my running playlist that are great to run with. Embarrassing if anyone were to hear me listen to them, but great. One is 2 Legit 2 Quit by MC Hammer.
I am also big on 80s music, so the Flock of Seagulls works for me.
When I was training for the marathon, I had a whole list of songs on my walkman that I listened to that I loved. I can't remember them all, and wish I could! One was Enigma, the first song on the CD, I think.
So many options. I love the link that was suggested here to Fitness mag. Good luck!
