imo, your just being salty
valid opinions can come from people who are great or just flat out wack... i try not to put too much weight on a persons skill or their own work for this reason, because that can greatly cloud your ability to receive what can be a valid opinion.
at the end of the day it's all about sifting the wheat from the chaff; even your gut instinct requires objectivity on your part.
its a hard thing to accept though... i get an occasional criticism that makes me say, "what the fuck?" and sometimes i'll make an attempt to apply it, and sometimes i'll dismiss it- it all depends on if i think it furthers my music.
certain people destroy their on credibility. for example, a few years ago, this cat told me he didnt like the "piano" in this beat i made. there wasn't anything resembling a piano- the part he called a piano as unmistakably a flute, by miles. there was nothing remotely piano like about it. his credibility went to the gutter at that point. that said, some peoples critique come with a grain of salt.
besides, whose to say what "par" is? i hear some of the worst shit get high praise
some people swear by andre nicotina but i can't find a solitary redeeming thing about his work
