I agree.... Music is great for different emotions. But, when I'm depressed I tend to listen to various artists. Too many to name... but, I have noticed my music taste does change when I'm depressed.

One artist in particular is Emilie Autumn. I've notice if I begin listening/obsess to her I'm heading into a deep depression. But, it's something about her music that I love and must listen to when I'm depressed. It's very hard to explain.
