No matter how impressive a popular song is, a mainstream idiot won't look at it in a smart way ^~^ Also it's not really just popular music that's destroying society, it's really the fact that everything's being dumbed down. School, Television programs, music, and maybe more I can't think of.
Anyhoo you pretty much spoke my thoughts on mainstream music. Good stuff exists...somewhere. Mainstream (let's just say stupid from here on out) people like pop/rap because it's in fashion. Stupid people listen to the music they listen to because it's fashionable. It's all a fashion sense to them, almost like clothing. We here at OCR listen to all the "weird" stuff we do because we actually have our own minds; we don't do things because they're popular because we have our own real opinions. Why do you think I go on forums? Because I can talk to many people who actually do think for themselves.
Now of course some people DO think for themselves and actually like this stuff. My sister likes Pop music and 80's music (mom's influence >_>) but hates hardcore rap like Li'l Wayne and whatnot. That's just what she likes and at that point I can respect that. It's certainly not what I'm into but at least she has her own opinion.
Anyway that's all I have to say.
