The early 80s thrash scene in San Francisco (the one that produced Megadeth and Metallica among others) wasn't exactly DS controlled up until the early 1990s. The DS failed miserably in my opinion ... I believe the reason for that is that thrash is inherently counter-culture (has lots of roots in punk as well as hard rock) and it's too damn complex. It doesn't work well with liberal philosophy. You need loads of repetition to put people into that trance-like state. Great thrash/metal isn't like that at all.

I remember MTV promoting heavy metal/thrash and rap heavily in the early 1990s. Most of their pop music was moved to VH1. Rock the vote started around this time (another left wing non-profit) too. It's pretty clear that the DS was at least trying to capture the genre to exploit it.

Since Megadeth is my favorite band of that genre, I'll focus on them ... Dave Mustaine (Megadeth's mastermind) basically supported Bill Clinton (he said Ross Perot early on, but admitted that he voted for Clinton) ... most of their songs on Countdown to Extinction (released in 1992) had themes that the left were using against Bush during that election (not like Bush was any better of course, but they never attacked Clinton). There was also the "99 Ways to Die" song Megadeth released in 1993 (or was it 94) that had a video that was basically a commercial for gun control.

Some other things I remember from that era ... the band Nuclear Assault released a song about the frigging environment. The video had the lyrics scrolling across the bottom of the screen with their one eyed mutant bouncing on each word. I recall Metallica giving George Bush some shit (again, Bush deserved it, but they never seemed to attack Clinton at all). I also remember a lot of those stupid hair bands ... many of them one hit wonders ... being lefties when on camera.

The DS seemed to realize that metal wasn't the way to control people some time in the mid 1990s ... they shifted their focus on pop and rap. I swear it's the reason why rap music, club music, and pop music all have the exact same structure these days. Most of the big labels dropped their metal acts when their contracts were up.

Megadeth did a 180 on politics right around the end of the 1990s. Some of the songs they released in the late 00s basically predicted today. Check out the song "Washington is Next" ... you'll see a LOT of familiar themes we see today ... that song was written in 2007. Their album Dystopia was frigging brilliant at predicting today's events too (that came out in 2016) :-).

Many other bands from the era seemed to be apolitical or pissed off about everyone in any form of power ... Iron Maiden, Motorhead, 'most' of Anthrax (Scott Ian's side project SOD and its cousin MOD are fucking classics :-) ), Slayer ... none of them seemed to do any bidding of the DS and they're pretty much the exact same today.
