Podrunner

In trawling through the free downloads from the iTunes store, I came across Podrunner - mixes of music with a continuous beat. Now whilst it may be the most hypnotically moronic music I have ever listened to, I have been surprised at how good it is to run to. I tried a mix at 170 beats per minute first, which was great. Yesterday I tried 140 beats per minute, but that was far too slow.
