A) What Morning said, I remember that, it's true
B) Everything I come across that's "modern" is full of swears, love, and just plain crap
C) Rule of Thumb: If you can't whistle with the lyrics, and keep the beat by snapping, it's not that good
D) If you look at the graph I posted at the start, you can see ragtime at the start: low, The greatest things to come to music mid 50's to mid 70's or so: epicly high, and lastly, anything made since then: down the toilet.
As to being under 15, what of it? At 14 I'd figured out how general relativity could be used to time travel without breaking the laws of physics (namely going above light speed). So if at 14 I could do that, whose to say someone half the person I was wouldn't know something about music, and be able to give a vlid opinion over it's decline/ascent?
