Agree, but just don't try to spin metal as topping the charts. Like the guy in the '80s culture rant said, it didn't. It didn't in the '70s, either. Let's give a true overall picture of the cultures, not of pockets of fringe fans here and there.
Dio's second album, Last in Line did reach #28 on the Billboard 200 in 1984. Quiet Riot's Metal Health reached #1 in 1983. Dokken's Back for the Attack topped out at #13 in '88. Metallica's Master of Puppets peaked at #28-with NO radio airplay. Iron Maiden had several top 40 albums, Peace of Mind reached #14 and Powerslave (their two best IMHO) reached #21.
Also-keep in mind. There was a LOT of metal on MTV in the 80s. There was also Springsteen, Duran Duran, Culture Club, and all that other pop crap, but metal was definitely on the air.
But no, the chart toppers were largely "pop" acts as they always have been. Hence the term "pop" which is a short form of "popular."
