Who the hell are you to ultimately decide what music is "quality".
"Quality" of music, is like "quality" of a novel or poem. Just because you picked up a crayon, and decided to write a novel, does not mean it will be of "quality", compared to the work of others.
I think in todays society, it is not much about someones opinion, but rather their ignorance. People really no longer have an opinion of their own, they just follow what everyone else is doing. "I really like this shirt.....hmmmm Lil Wayne doesn't own one like it, so I cannot buy it"
