mhnso, I think a lot of us feel the way you do. It's fun to "categorize" and "rate" things, because it's one of the ways we can discuss things of mutual interest. However, yes, music is something that can be deeply personal, and it explains why some people absolutely love things that you would cringe at, and vice versa.
I was on a Beatles discussion board several years ago, and what we used to do was, our little group of anywhere between a half dozen to a dozen, queue up a Beatles or solo album at home (on our own individual CD players, tape decks, or even turntables), and "listen" together...commenting as we listened on IM. Remember the now defunct (I think) service, Prodigy? Anyway, it was always illuminating to me how we could all listen to a Beatles album, or individual track-- and all of us were HUGE Beatles fans, obviously-- yet come away with the most amazing differences of opinion.
I remember one night, after listening to an album, saying, quite innocently, "you know, the song "Little Child" reminds me of "Tell Me Why." One of the people on the board agreed with me, but another one jumped all over me, citing all the technical clap trap of how "different" these songs were structurally, and melodically, and yada yada yada. Well, perhaps this guy was right...but he didn't get my point. To me, the songs had the same kind of "feel" to them. Another example would be "Every Little Thing" sounding a lot like "Tell Me What You See." Other people would scratch their heads and say "wha?" But, to me, there is a strong similarity in the way they sound and how I "hear" them.
So, it's just opinion in the end. No one can get in anyone else's heads (or ears). Which is why I am amazed how groups like The Beatles, or Frank Sinatra, or Elvis, or whoever became so popular. What was it about these artists that set them apart, and made them so appealing on such a mass scale? Surely there were countless others around their periods who were, if not equally talented, nearly as...yet, they toiled in obscurity, while the others became popular, famous, rich, and trendsetting.
And, I've babbled on enough. Let me read this back and see how full of myself it sounds...yikes!
