Rock and Roll evolved and diverged. The original Rockabilly, Blues Rock and Skiffle each sounded different although with some commonality, and they were very different from Surfer music, which were different from the Acid Rock of the late 60's and 70's. There were regional differences as well.

I tended to enjoy tunes that were not necessarily pop hits. My brother and I used to listen to Casey Kasem's American Top 40 on a Sunday morning. I'd often wonder why certain tunes were declared hits, because I didn't care for them. Obviously, I had a different preference to the music industry.
It's a matter of personal taste, and one simply has to listen to different genres/groups and discover one's favorites.
