Whether it's old or not Chips, is not an issue, if it's good it remains good and yes the seventies and eighties were the best years for popular music, most music lovers will agree to that, not the garbage they now roll out.
Cloudy that Simon and Garfunckel "Hello Darkness etc" is Sounds of Silence, yes it's one of my favourites too.
Mike and Mozart, yes cannot fault any of those and yes I enjoy all of those too.
It's actually very difficult if not impossible to put them all down...it depends on the setting and mood at the time.
I enjoy folk and traditional a lot too. Love military marches too and the pipes. Cannot help it, Scots and Irish blood in genes.
Pavarotti, Bocelli, Mario Lanza as tenors and Dmitri Hvorostovsky baritone no question some the best music ever sung. Also are crazy about Andre Rieu's concerts, Bolero being a favorite.
But classics is too vast and needs a catergory of it's own. It is indeed superior music.
