Bless your heart.Still sounds pretty much all the same to me. "Funky" and "fresh" are definitely subjective.
I don't recognize "Leila" or It's So Hard" at all, I can't imagine they were much of a threat to Fleetwood Mac's hits which everybody knows.
Springsteen's range is miles wider that ZZT's.
Maybe it's a global thing and Texans don't understand?
