Don't disagree with that survivorship bias isn't real, everyone thinks the music of their time was the best. Still it's not the only factor at play here, because the music industry was in crisis in the early 2000's and its revenue dropped in half. That is a huge drop, and the less money in the industry, the smaller the pie that goes towards all types of projects, from Tubthumping to Smashing Pumpkin's Rocket.

But do agree that most of the 90's was still pop music (just looked at through the top 100, forgot about most of those groups:)
