Kaiser Chiefs are always good for a bit a pace work.
Although, I am really into 80s pop at the moment whilst on the run, for some reason it seems to work. A selection of my playlist from last nights speed reps:
Kraftwerk (the model), Flock of Seagulls (wishing), Specials (ghost town), Blondie (call me), Men at Work (down under).
I have only had my iPod for a short while but am seriously loving it. It certainly can help when trying to push those last reps.
