I know my knowledge of what is good music and bad music is top notch (everybody has that ability), and I've got to say the ratings in the AP dont tell the truth at all. All the really great songs I've found, where you can hear real talent between the instruments - have really bad scores and dont show up on any charts at all.
I KNOW this is because jaleous really ass bad artists get tired of being out-ranked by the really good ones, and does some serious zero-bombing and what not. This is why the AP should have a staff with "pro-reviewers" that award the really good submissions, and ignores the incredible amount of (face it) pure shit thats in here. That way it would be possible to find the good artists and the great tracks without going through all these forgettable score-boosting really bad songs :)
The only really good artist I see doing good in the AP (score and reputation-wise) is ParagonX9.
And my morning-cigarette rant is over :p
