So, after reviewing the Top 100, assuming that I would recognize most of the songs, I DIDN'T.  I started at #1, going to #100.  I only recognized 4 of the first 25 songs, maybe 7 of the artists, and stopped there.  Either I'm REAL OLD or  Billboard and the R&RHOF are very opinionated - very little objectivity.  You alluded to that in your introductory posting (opinion and ephemeral category).  What's even more interesting is I have been making an honest attempt at trying to stay on top of the weekly singles #1 song in the Billboard Top Pop singles right up until recently; maybe I've been focusing too much on the Adult Contemporary genre including Ed Sheeran, Taylor Swift, Maroon 5, Adele & Bruno Mars as well as recent recordings by oldies artists that still have talent, including The Stones latest (Hackney Diamonds album), Dylan's one and only #1 single in the US, Murder Most Foul, released in about April 2020.  That said, I still have an interest in hard rock stars and others on the periphery.

Too many years of music to compare. Comparing the music of today to the music of yesterday is like comparing apples to oranges.
