Today's music is killing youth

I frequent Amazon.com for music and products and lately I've been looking at the reviews by a ton of people. I must tell you that the reviews that I see for some of the classics of all time are completely absurd. I think today's music has gotten so bad that people are growing up with what they think are classics! Someone had the nerve to say Led Zeppellin's IV was outdated and crap! WTF! Sure it may be old but you people need to appreciate where your modern day music came from. Today's listeners just don't appreciate what "good" really is. The music industry has done it to themselves for releasing so much crap that they've killed America's ears. I am not just sticking up for Zeppellin because I am a fan. I listen to tons of music and yes I did grow up during the grunge era and may be jaded towards that style but I am such a music connoisseur that I've learned to appreciate music as art. I like to take it for what it's worth and how the artist wrote it. I understand there is definitely a lot of junk out there and that's the whole point of this thread. It's getting harder and harder to find good stuff so you need to take a step back and take a look at what good music was and still is.
