Yep that's fair enough. I should say that I also like joyous music for the same reason, but only if I feel that the joy is genuine. I think that's the key for me, I like to feel a real emotional connection to the music, and not some contrived travesty. I don't much mind what the emotion is. This may stem from having battled with depression for a long time. Depression makes you numb. It's hard to feel happy, but (interestingly) it's also hard to feel sad. It's hard to feel anything, you turn into this apathetic shadow of a person. Music sets me free!
