This is a message to Hal Jordan, you seem to have completely missed my point.
First of all I'd like to inform you that you are in fact INCREDIBLY biased, so you might want to change what you think on that. I made my point trying to be as objective as possible, and perhaps I could word it slightly differently. When I say music is evolving, I DO NOT mean that everyone evolves with it, I thought I'd explained that bit OK. I'm not saying that music changing means you also change your tastes to go along with it. You're comparing modern day music with music of a different time and you're making a judgement on what you think to be better. That unfortunately is your own subjective opinion. As long as there are people who like the new stuff, then it can never be deemed to be absolutely bad. You may not like it, but while there exists someone who does like it, you'll never be objectively right.
If someone wrote a new song and played it to a million people, and of those million, 999 999 hated it, but 1 person loved it, then that song is not absolutely bad. The majority can say all it wants about how much the song sucked, but unless everyone in existence hates it, it's pretty difficult to say it's absolutely bad right? You may well believe that music from the 70s and 80s was superior to modern day music, but I don't think so. I don't hold a lot of regard for that particular era, bar one or two timeless greats, but even now timeless greats emerge. Music is about finding something you like, and what most people fail to do is recognise that. So called "experts" slam artists, saying it's "not real" and that they're completely phoney people. Who are they to say so? It's just like film critics. How many films have you enjoyed that received a bad review from a famous critic? Personally I've seen quite a few, because just like with music, there probably aren't many people who like EVERY genre of film. This being so, if you don't like Sci-Fi, are you going to give a new Sci-Fi film a stunning review? NO, because you go with a negative mind set thinking "god, another sci-fi flick, what a waste of 2 hours".
Music IS evolving, it's changing to the dismay of some and to the joyous discovery of others. You say that grunge killed glam rock - NO. In your mind you see it as death, but more objectively, it's just a change - some people prefer the new thing to the old, so you can't say for sure that the music has died and you can't say they're wrong. You'll never be right, and neither will I. Subjectivity is such a pain!
I stand by my point, and in fact, will alter the wording:
MUSIC NEVER DIES, IT EVOLVES!
