it gets me pumped, and when iam really into a good song you can tell, I wont stop riding and then I just push myself. as far as the ear peices I use the Sony sport ear phones, they wrap around your ear then go inside, every now and then I have to adjust them, but iam trying to figure out a better way of keeping them in.....just short of using all my military skills and using duck tape......
