Having played in numerous bands and been around a lot of musicians, I can tell you not to give too much credibility to individual song lyrics. Musicians try to be cool.
Black Sabbath (amazing band) used to be a blues band. They watched a horror movie one day and realized that people like to be scared. So, they started creating scary music. A lot of times, it's not more complicating than that. Dark songs aren't necessarily connected to The Cabal.
However, the big picture of music is VERY important. The Rothschild Disclosure revealed that they don't want music that exceeds a 6th grade level. being consumed by the public. They've certainly accomplished that with current rap and pop music.
The CIA has been VERY involved in popular music in America. They definitely killed brilliant guitar player Randy Rhoads. 7 in 10 plane crashes. Pilot ran missions in Middle East.
They likely killed Hendrix, Lennon, and many others. There's a guy who wrote a book on the CIA killing musicians (can't remember his name) who said the CIA often kills the most talented guy in the band.
I watched this YouTube video last night about saying the CIA created the 1960s music scene. Given their history with LSD and mind control, it makes a lot of sense.
