My *favorite* music is that of the early 90s, when I was indeed in my tween/early teens, but I tend to break with other middle aged folks in remaining stuck exclusively in that time. I’ve found lots to enjoy about every era of music in my lifetime (and many eras before it).
For me TV was mostly best before the reality TV revolution. Society was best in the months before before 9/11. Sports were best before so many leagues greatly expanded playoff eligibility. Gaming was best during the PS3 era (2006-13; mid-20s to early-30s). The economy is best right now.
Yeah, I still listen to a lot of stuff from the 90's, but thanks to places like Bandcamp (and money!) I still get tons of new stuff and it's all really good. It helps that I got into different genres over time, so I'm always discovering new things.
