it seems to me Pavel is looking for acceptance for his taste. (having group's acceptance can be reflected on your self-image)
what many people seem to lack is respect. having a topic "psychill sucks" is purely negative in its meaning and creates 1) bigger delusions of your "better/right" taste 2) negative debate
music has no absolute value, and gets meaning only when one gives it an opinion. So you see, one should learn to enjoy the possibility of getting something out of music, and leave the negative aspect out of it since it just adds negativity.
