I actually think classical music is MORE relevant with each passing decade. As each generation gets older it seems inevitably we all want to relax and listen to classical music --- how many times have you heard your parents listen to it? And we all get old, no matter how we try, so it's sort of inevitable that we will all, at some point, maybe not now or even soon, but at some point end up listening to Bach, Mozart et al, even if it's only on Snooze FM when we're 80! Can we say the same about any other genre? Think you'll still be listening to rap, death metal, nu-jazz or even prog at that age? Well I might be listening to the latter, but you know, those long keyboard solos might just send me to sleep at that age!
