FWIW most of the top charting music of the 90s, 80s and so on were also "worse" and have mostly been forgotten. Few songs remain popular or regain popularity. A lot of chart hits are really just springboarding off "you had to be there" cultural moments or experiences or simply a general "vibe" that are fleeting and trivial enough not to stick around even in nostalgia.

As an extreme example, I'd argue the popularity of David Hasselhoff's I've been looking for freedom in Germany is almost entirely a result of "retconning" (if not fabricating) its supposed popularity at the time of its original release. It would have probably been forgotten entirely if it hadn't been rediscovered "ironically" in the context of ridiculous claims about its influence on the fall of the Berlin Wall. Heck, I remember owning a casette of the album as a kid only because "it's the guy from Knight Rider". For adult women his claim to fame was co-starring alongside Pamela Anderson in Baywatch as one of the few men regularly appearing bare-chested on daytime television - I'd say his musical talents played a very small role in his original popularity and it's telling nobody remembers any other songs than the one he performed on a TV show. He was never considered good, he was just a familiar face (and body) and made a catchy tune.
