Christi, I go to Limewire.com. It's a file sharing service. I have all kinds of great running music on my MP3 player.
Tina Turner, Mariah Carey, The Pointer Sisters, Chaka Khan, The Rolling Stones, Peter Gabriel, Madonna, I could go on and on. Choose cheerful upbeat songs that make you want to dance, I think that is the best running music.
