I'm probably the odd duck, but there's a lot of music I loved in middle/high school that I can't bear to listen to now and there is a plethora of music made since, especially in the last 10-15 years, that I love just as much or more as any of my long-standing favorites.
There's no lack of great music being made today. If you look for it you will find exciting new acts every time you search. Great music didn't end when we were kids.
