Manson...
Best music is silence. I'm played on bass in past with real outdoor performances. But nah. If you want keep thoughts clear - don't listen anything at all.
If you listen because office too loud - is another story. If you maniac in some music (too addicted) - is another story.
When, i'm was young - i'm sleep in headphones by similar music including manson sometimes.
After 10 years of silence: i'm recommend - silence with eventually listening what you really want, never to fill noise. You should hear own thoughts first, and music - is last what you should hear/consider.
There is exist exclusions for me: the kills, and others strange bands: but still - don't trash own head without reason. This music is too aggressive and you never may operate at same level as without.
You can't live without music? Is lie.
PS: Actually music style is no matter.
PPS: Is not offtopic: my choice - SILENCE, even while i'm too addicted to few bands....
