The basic answer for me is drive, what I like to do is play the bass along with it (by along I mean try to get something right), I listen to music lying in bed with headphones before bed which is maybe not a good formula for sleeping well, but it's an opportunity to listen to music that I often take. No wait, come to think of it, what I do is smoke my hookah and bang my head... yeah, that's exactly what I do! SoOO fucking METAL!!!
