But you're talking about the downfall of MTV, and nobody else fucking cares about that.
It is not just MTV. Ironically most young "metalheads" I see today who listen to the likes of Marilyn Manson, Cradle of Filth, and 'extreme metal' in general tend to fall into the camp of nihilistic, wrist slitting, emos.
I'm sure not all metal today has this 'vibe' (I myself wouldn't know because I listen mainly to metal from the 80s/early 90s and before - like Iron Maiden, Priest, Motley Crue, Def Leppard, Megadeth, Dokken, Ratt, Metallica, Pantera, Cinderella, Skid Row, Aerosmith and others).
Metal may have always had something of an "outcast" chic, but in the past metal was associated with more of an outlaw, rebel aesthetic.
While today it's idea of "rebellion" has been watered down into the same camp as the typical emo/goth/social outcast subcultures; something for a bunch of nihilistic, suburban, virginal, millenials to "identify" with in high school just for the sake of negative attention.
Any idea why this is? My only thoughts are that it dates back to the "grunge" shit of the 90s and the entire "alternative rock" schtick which followed, which likely had a big influence on metal as well. The lyrics in a lot of extreme metal are of the same garden variety content as the grunge/pop punk schmaltz too - except we just have some guy screaming or growling about how much he hates himself because his girlfriend dumped him instead of singing about it in a high pitched nasally voice. Heavy metal from the 80's dressed like queens sure - most people in the 80's dressed gay as fuck. That said, 80's metal bands were the epitome of Alpha Male. Not giving a fuck, making tons of money, partying and doing whatever they wanted, and fucking tons of girls all the time. I'm not sure if we'll ever see a time for metal like we saw in the 80's/early 90s.
