Been thinking a bit about this, popular music (the ones that hit top 100 charts or whatever) never has lyrics that point out real problems or point to culprits and how they're fucking our shit, which is very easy to find in punk rock and some variations, as well as rap.
Of course, part of the problem are the record labels themselves, which often hold artists "hostage" in order to profit off them. Bigger ones will obviously prefer to avoid having such lyrics become popular.
Still, there seems to be absolute zero songs in certain genres that even come within 10 meters of talking/singing/teaching/bringing awareness about situations that affect a LOT of listeners, even from far away, and would be extremely helpful in spreading some knowledge.
Granted, doing so is easier said than done, a catchy tune that calls out big oil's many attempts to burn the world, or big pharma's frequent price gouging, aren't things "any idiot" can come up with. But that nobody outside "angry" genres seems to be doing it is what saddens me.
I think it's because the top 100 or whatever chart you're looking at is meaningless these days. It used to be a fair representation of what people were listening to, I remember people taping the top 40 off the radio on a Sunday to listen to through the week, everyone was on the same page regarding new single releases.
Now we're atomized, I don't even know what the #1 single is on any given week and I don't care. I've got 30,000 tracks on my home server. There's no new artist who can speak for a generation like Dylan or Woody Guthrie could in their day.
Not to mention those charts are easily manipulated nowadays. The criteria changes depending on who they want to put at the top.
It's a byproduct of diminishing sales of singles. You couldn't rig the charts in the 70's or 80's without spending a small fortune.
