Which of the 4 decades are better 70s,80s,90s,00s (Music Wise)?

Definitely the '80's. I loved Sting, Gowan, Level 42, Thompson Twins, Twisted Sister, Duran Duran, Aha, Men Without Hats, and yes...even....Boy George. Never much liked who you listed with the exception of cyndi Lauper, but man, those were awesome times for music.
