Positive moods by negative music?

"Oh I'm depressed, I want to kill myself, but what could be:? Katatonia never heard debug times .... (three minutes later), wow I feel much better, and the one after just one song by I previously unknown band. "

It's really amazing how this gloomy music builds me positively. The create a few melancholic bands. Katatonia able to give hope it with their music, but there is a light at the end of the tunnel and it is worth continue living.
They sound on this album as a grim version of Porcupine Tree (by that I mean the progressive parts and vocals), mixed with classic metal riffs and a touch Gothic.

The claim of the musician enormously, here were real experts at work. ROCK ON!
