I will not workout without my Ipod either. If it dies then my workout is done. My music keeps me going. I like a wide variety of music that gets me going. I usually like fast hard music like these to keep me hyped up. Sometimes I would go to the gym feeling so tired, but after 5 minutes of listening to this stuff then I get a burst of energy. Linkin Park, Papa Roach, rap,etc is good for lifting,but I have to have my techno/house during cardio.
