Twisted Sister, I always seen them as one of the first popular bands on MTV like Quiet Riot that had just a couple of popular songs and videos during that time. And I think they're both really overrated these days. They were never anything like that back then, just..so..so.
Why all the hype now?
Twisted Sister and Quiet Riot are pioneers within their own right though, I admit.
Motley Crue vindicated themselves with Dr. Feelgood. Slave To The Grind by Skid Row is still kinda cool.
I think Ozzy carried the best music through the 80s and 90s.
