Kind of a weird question, but I respond very well to music when I workout. For example, I had just finished my Triceps and still had to do forearms but I was really tired and wanted to go home. A song I had only heard once and really liked (Nickelback: Far Away) came on and gave me that little extra motivation to continue. It just seems certain songs remind me of certain things (like for this one, my girlfriend) and gives me the extra bit to dish out...
