I think the answer can be found in Closed Captioning. I was just watching a TV show with the captions on and it said "Scary music" "Sneaky music" etc.
The reality is that different music goes well with different activities. If you go to Amazon Prime music, there's workout music, dance music and reading/studying music.
Hard Rock - music to lift weights.
Hip Hop - music to dance.
Classical - music to think.
Which of those three do you see modern Americans doing the least? There's your answer.
