I am a loony toon longer than the day but I have had this just barely missing conjoined corners of my mind. It just hit 90 degrees and I gotta ask a bunch of internet people. This is only one example but I will suggest conscious listening to the radio when you choose to to see this in action. Consider attention spans, if we could measure mine is shortest so I win please carry on... When we have control of what we are listening to this is probably less likely but I have done it to myself with an iPod years ago.

If you care, this is a two and a half hour long playlist of '90s songs, some I do not recall having ever heard others have been "my jam" more than once with proper liquid encouragement, cheers! What I wish to bring to attention is how the content changes, back and forth. Love and hate, cold resentment. Again, I have noticed this with local broadcasts as well. I am curious about possible suggestions as to why this might be, though I have my own ideas as well.
I often find myself blaming the rap, but if you go far enough back it wasn't always the mumbled garbage we get today. Prior to marshal mathers trying to make a name for himself a lot of it slapped pretty hard and in a good way. A few were even dedicated to unveiling the evil of the industry before it was huge. They offed the ones that wouldn't comply and over saturated the music market with hot garbage.
This isn't rap but it is a song that I used to listen to an awful lot without ever really paying attention to it. I got kinda drunk the other night and it popped up in my feed. I WAS FLABBERGASTED! I actually heard the words. https://www.youtube.com/watch?v=Zz-DJr1Qs54
Pumped up kicks was another. Ultimately the individuals fault for not paying attention but someone has most convinced that attention is not necessary.
