Most (if not ALL) of the the-old-music-was-so-much-better diatribes come from people who never listen to anything new. Or listen to what is on a limited radio playlist for about 3 minutes (and then make their pronouncements).
There is a LOT of very good music being produced today. A lot. And a good amount of it sounds similar to stuff done "in the good old days". There is also a lot of new, innovative sounds being created.
But you have to actually be listening to it to find it...
as I said in the lyrics of one of my songs.... "You can find it in the honkey tonks and internet downloads" Yeah, there's good music being written and recorded.... but you have to go looking for it because it sure isn't pouring out of the radio these days. I think we can all agree on that.
