Up until the 2010's happened, were the Late 1990's/Early 2000's the worst time ever for mainstream music?
I think they were. I mean that was the era of teen pop singers, boy bands, cheesy rap music, post-grunge and nu-metal. It was the era when the whole era when everybody was trying so hard to be a bad boy or bad girl and failing so hard at it and looking back at this period is so cringeworthy these days and the more I learn more about this awful period, the more I hate it.
Thank god the Mid-to-Late 2000's saved us for awhile from this terrible period. Sure the 2000's weren't perfect, but they were much better than the cultural wasteland that is the Late 1990's/Early 2000's. And I think this awful period for pop culture deserves all the blame for how terrible things are today.
