Mm, if you lower the volume the music gets boring, yes -- so who says you have to lower the volume?

I sometimes like to listen to "constant barrage" noise pieces as background. Stolen Light's "Symphony for Marimba Opus II" is a good example. Although noise has a "harsh and painful" connotation for many, I find it somewhat calming, particularly on closed headphones.

But you're right, the stuff that oscillates between quiet and DEATH has its place.
