What is 'culture'? It's a learnt behaviour(?). If the process of learning is an essential characteristic of culture, then teaching also is a crucial characteristic. The way culture is taught and reproduced is itself an important component of culture. So the fault lies at each level. If you don't expose the youth today(again, today is to maen at any point in the history of time. In our days also we were youth of 'today') to the tunes you loved, how are they going to appreciate? And it's not mere lsitening, they have to be shown the nuances of the compositions in a manner that might interest them. No one likes advice. It has to be coated in a form that is acceptable. I remember a friend who introduced the evergreen music to a youngster. And how? Knowing the interest of the youngster in rhythms, he picked up a Geeta Dutt song "Hum ne dekha pyar mein do naino ki maar mein" from "Guest House" The song had a rhythm, a certain naughtiness to it, and was fast. The person in question liked it so much and became a Geeta Dutt fan. She is still a fan. The point I wish to make is that some things have to be brought out. It's in there.
Another aspect is that not everyone will have the same choice. If every-one started loving the music of the golden era only, what will happen to today's composers? they are surviving and hitting the charts because they too have a following. It takes all kinds to make the world.
And if there was no such divide in choices, we wouldn't get a topic to discuss and mull over the 'golden' songs, will we!!!
Just a few thoughts after forcing myself to take a neutral ground. "One has to get out of the picture in order to see the perspective."
