I have just downloaded spotify on my phone. They hav a load of dif choice playlists all for running. Aimed at dif tempos. Put together to help with your pace. I found out aswel that spotify can work out your pace and search for music that matches that. But it must be on the Iphone as i cannot seem to find this option. Also you can sync it with runkeeper. Got some good songs to get you going. Cant wait to try this out. tomorrow as I start week six.
