I don't use music when training at all. I used to have different up/down beat playlists. Most of my events I am not allowed music etc so tend not to train with it.
Trance, trance and more trance! I just fund the upbeat mood of most good trance music helps me push myself that little bit more. It's pretty much the only time I listen to it.
Metal. I have a mixed album of Metallica/One day Remains/Avenged Sevenfold/Buckcherry/Alterbridge/Shinedown/Stone Sour/Seether and a few more that makes me want to throw stuff around and pumps me up t do that 2 or 3 extra reps.
