Teenager in the 90s. Man was everything optimistic in the mid to latter part of it too. I was never very wild - basically a nerd doing Star Trek, reading, D&D, anime, and TV shows in general. We live rural - in many ways we were 20+ years behind my classmates in school even though they were very slightly less rural (I mean a village of like 1,000 people and a class of like 78). We still only had OTA 4 channels of which one was PBS. We had rotary phones (cause why replace what's working) and party lines (till the phone company made them drop it and the savings in like 2002?), we had 33 and 45 records and cassettes - no CDs either. VHS tapes. I got into reading books cause of that - didn't have multiple TVs, the one TV was a 12" B&W my dad apparently bought used in like 1979 or something till in 1993 when we finally got a 19" COLOR TV, but still only B&W for "my TV".
Though I was way more techie too, maybe from Star Trek fantasies? I pushed and pushed and got my parents to finally get me a Sega Genesis in 95, and an actual IBM computer. 2 years later I convinced them to get "the Internet" via dial-up. We had the Internet before we got rid of the party line lol. That was fun let me tell you. I feel in some ways my family kind of went from the mid 70s right to the late 90s in tech and culture. I was into search engines and MP3s pre Google.
I do feel like a bit of a codger ahead of his time when so many things are "I was into xx before it was cool", but maybe everyone feels that way as they age.
Music wise I have to say - growing up it was all 60s folk and rock and roll. I got into some Aerosmith through some friends and then hit on Nickelback in 99, still like them to today (FIGHT ME). I also "grew up" with Brittany Spears and the boy bands around the turn of the millennium. I never really got into rap at all, though that seems to have been slowly "taking over pop music" since 2001 or so that I've noticed. Although now Pandora is trying to tell me my Nickelback channel should really add some sort of Country to the mix, which is... weird. Though I like Country too, it's a completely different vibe IMHO.
