I listen to just about everything besides rap, well shit i listen to some oldschool rap from time to time.. But lately i've been listening to a lot of classical music, like bach, beethoven, and mozart. Mainly those 3, and to be honest when i listen to that stuff on the car ride to the gym i have an awesome workout. It just calms me so much but at the same time some of the music almost seems dark so it psyches you up
Just thought id share, maybe it'll work for you guys
