I have been trying to create some great playlists on my iPod for running and cross training. I think I finally have some good songs, but I really wanna know what music really pumps you up to push a little harder during your workout? I’m really liking the song, “Gotta Be Somebody” by Nickelback and I saw another reader likes “I’m Sexy and I Know It” which I just downloaded! Seems like these 2 are gonna be at the top of my list. What do you suggest for me?
