I've noticed the same thing with music as well. Crazy Train by Ozzy Osbourne seems to me more like a song about him discovering a truth he shouldn't have.
"One person conditioned to rule and control, the media sells it and you live the role"
But I listen to mostly "heavier" music, such as Tool. Their stuff is pretty cryptic, but some good ones to look at would be The Grudge, Lateralus, Parabola, and if you want to tie in ayylmaos, then their 14 min song Rosetta Stoned has got you covered.
Honestly, it would take a pretty long time and a lot effort to decode Tool, and who knows how much is truth, and how much is not. Lots of symbols anons should know though, such as the star of david and pentagrams showing up. The official video for porabola is absolutely a good starting point. I think. I almost seem to think that these need to be watched in a certain order for it to put together a bigger story. (probably easy for those who have the actual album order, and not just watching randomly from youtube.)
I haven't really bothered to actively put the pieces together yet, since I'm honestly quite too lazy to bother.
Long story short, it's everywhere. A lot of music is just distractions, some are probably artists just looking to make cash, and others are people who know things, things that can't be stated bluntly, or straightly. It's those that know truth ,though likely only portions, and are likely just as confused and lost in many regards as anyone else, who are the ones to listen to.
