In a word NO
Great music never dies, the kids always find something they consider is better than their parents listened to. ie rock & roll is dead ------- long live rock & roll.
My kids are listening to hardcore, electro house , funky house and hiphop. they still stop and cock their ears when they hear the trance from my logitechs.
Last week my mobile rang while I was at work, the ringtone is Kaycee - Escape, and this old lady heard it, in the poshest elderly voice she said "Oh what a lovely tune" I didn't have the heart to enlighten her.
Dead No. maybe unloved by the latest generation but not dead
