Depends on music and how you listen. I find that while reading book, I can listen trance infinitely long (low volume), but not while driving a car, for example. While falling asleep, or just day-dreaming I can listen dub-step, but not while reading a book. While doing chores, I can listen classical music or chillout indefinedly, but not in other settings.

PS. in a car, I am most tolerant to (classical) disco.
