I've been saying this when chatting about music to friends for a long time without really realizing it. I always named that prominent snare drum sound as something that really hit its peak in the 80s and died not long afterwards but couldn't point to any reason why other than general music production leaning more and more bass heavy.
I have a playlist on my phone that is the #1 billboard hit, in order, starting from about 1963 until present. I listened to it in order one time on a long car drive and it was pretty eye opening - moving from the 60s to 00's the bass level increased a huge amount. Those are pop songs too but I feel like even the hard rock and metal tracks have been doing the same thing for a while.
