It had the best of the best in popular music history.
You had Funk, Soul, R&B, Fusion, Latin Jazz, Progressive Rock, The best hard rock, the birth of heavy Metal and Punk, the best ballads, the best sounding records and most innovating studio techniques. The best producers and most outside the box thinking artists of all time. Even pop shit like ABBA was good shit, great musicianship and masters at writing catchy tunes. Not the Euro trance electro shit that was huge in the 90's. Etc etc and etc... I could write a book about how it's not even close.
Look, as you know I was a teenager/young adult in the 90's and that decade's music still mean a lot to me, I absolutely loved it, the rock part of it that is. But comparing it to the 70's is wrong beyond words. Coming from ZoSo he could very well NOT be trolling.
