Well when I say best and worst, I mean in context. I check RYM for the ratings and check them out. Of course there's no obligation to agree. Example: The Satanist was RYM's top black metal album for a while, but my favorite of 2014 is Roads to the North. And RYM worships Burzum in that context and it gets on my fucking nerves. My favorite bm band is easily Immortal, the first bm band I ever tried.
But this doesn't change the fact that I'm always trying to look for the best and the worst music, in regards to how I view it. Basically, I start with what other people say about the best and worst, and then I check to see what I would say, and if I agreed.
So for future reference, if you see me say I'm checking for the best, just assume it's in internet context. If you see me say I believe something is their best, it's always considering high quality as opposed to popularity.
