I usually do mine to dance music, even though I don't necessarily enjoy it outside of studying. I often catch my thought process mimicking whatever I'm listening to, and the little hooks and dives have induced jumps and correlations that I'm not sure I would have made otherwise. 
I suppose this could apply to finances or long paperwork if you don't have homework anymore (or your work resembles it).
