To stick to the OP...

What we have to remember is that, all of these iPad using karaoke wannabes, or ear-splitting bar-rock bands are NOT playing FOR US.

They are playing for our children (or for many of us, our grand-children!). Now, I don't know about you, but can you think of much music that was really popular when YOU were a teenager or early twenties that YOUR grandparents didn't say was 'rubbish' and ear-splittingly loud, a sign of the End of Days, what is the world coming to, you would have been laughed off stage when I was a kid, trash..??!!

Kids have ALWAYS picked music their elders disliked intensely, in fact, the more intense the dislike, the more popular it would become! This serves to assert their independence, and to separate them from the older generation. Along with fashion, morals, art, literature, social behavior etc., etc..

Our grandparents lamented the loss of the bigbands, and derided the combos. Their grandparents lamented the loss of the orchestra, and heaped scorn on the marching bands and early dance bands. And THEIR grandparents probably derided that upstart Beethoven, and said what a raucous racket he was compared to that nice Mr. Mozart!

We are doomed to turn into the very thing we hated when we were kids. And our kids are doomed to hate the very thing that we only listened to to make OUR parents mad!

Me, I try to find that little boy inside me. I try my very best to see what is new from that boy's perspective. I still WANT to listen to stuff that annoys and irritates my generation. I want to see something new, even at the cost of what I am used to and familiar with. I try to listen to new music with my gonads as well as my head. I want to feel my feet moving, despite all reason.

I don't always succeed, but I'm trying!
