Music for a bad mood: go with it, or counter it?

When you’re feeling gloomy, do you want to listen to music that

(a) reflects your mood—sounds as glum as you are, or worse?
(b) opposes your mood—sounds all cheery and upbeat, cheers you up?
(c) is neutral—has no special mood to it, or doesn’t express a strong feeling?
(d) is none of the above—mood is irrelevant? You like what you like, no matter how you’re feeling.

This isn’t about specific musical selections. It’s about whether you want to hear music that sounds the way you feel or music that expresses the opposite emotion.

And what about when you’re feeling great? Do you love a sad, sad song?
