if you look for good music, you'll find it.
back when i was maybe 15 or 16, i was always saying: "man, there are no good bands out there anymore, led zep forever blablabla".
these are words of infantile minds.
it only appears as if there's no good music, because what we consider good music gets little to no airtime.
rock, back in the day, was mainstream music, it was popular.
nowadays, the difference is, rock music (the good stuff), is relatively underground and has to be found, it's not "everywhere" as it used to be.
but i think that makes it interesting.
it's beautiful, listening to bands like "Sahg" or "Witchcraft" for the first time (well, for me it was), because you've really found something special.
check out bands from the post-rock genre, they will blow your mind.
ope your mind, it's not all "man, only 70s is good, fuck the rest"...there's so much amazing stuff out there you've never heard.
there are good bands in every genre, be it electro, hip hop, folk, soul, rock, pop, metal...
i think the problem is the elitist attitude of the younger people, who feel special listening to old bands.
you're not special, you're not retro.
you've got good taste, that's true, but you're close minded and blind.
the best thing you can do is just enjoy.
get out once in a while, go to music venues, go to underground concerts, there are bands out there that will kick your fucking ass =)
my (long) two cents.
