Music

How often you rely on it?

Either playing some or listening to some. And if you play what do you indulge in?

Every day.  I use it to get the noises of industrial civilization (like rap and  hip hop) out of my head.  

Unless I am asleep, watching something or on a phone call music is always playing.

I don't listen to a great deal of music unless its on the radio, but play it almost every day, usually one of the guitars dotted around the place.
