I agree with Phil here. Altho we differ in that I review more randomly, not going with the stuff I like first but rather as it comes in, I'm also not inclined to flatly pan a release. There's certainly stuff that I don't like, but I'm not going to presume to be the great arbiter of what's good and what's not. Rather, my approach is that while I may not like or "get" something, someone else may hear the good in it. My comment in that case is that people should go have a listen and decide for themselves. I'm not a big fan of dark ambient, for example. But some folks dig it. So maybe I don't get what an artist like Wolfskin or Hyios are doing--to someone else it's gorgeous.
I don't avoid saying that something's not good. I just say it's not good to me. I have no intention of becoming the Pitchfork of the ambient world.
