What do you listen to when you are in a bad mood?
Do you rock? Do you rave? Do you foam at the mouth, smash the furniture and scream as loud as you can?
Or do you put calm, tranquil, mellow music on, to soothe the frowns of worry from your brow, sipping an iced tea and meditating on the sound of one hand clapping?
I tend to go the Nine Inch Nails / Trent Reznor route. I put on something aggressive, loud and fast - and then I turn the volume up. And then I turn it up some more. And then some more...
Stuff like KMFDM helps as well, but I have found in general rock tend to work better - headbanging, moshing, etc seem to alleviate my feelings more than just jumping up and down to something like "It's a Fine Day"...
So how about you?
