The Hot 100 (the Top 100 is long gone) is in effect a compilation chart being fed by multiple genres and even it is about to change yet again as evidenced by this link:
Upcoming Changes to Hot 100 The algorithms for chart placement have changed so frequently that IMO it’s hard to determine what the “top” songs are. If I was musing over how to write a number one song - hahahaha - I’d be focused on the metrics for my particular genre. And there are plenty available, e.g, Americana, multiple rock sub genres, and many more. Get lost in the one you’re most comfortable with and listen, play, write, produce, track the song positions - all is good.
