Compared to say the 70s, the 90s was pretty bleak. A bit of good grunge, a bit of good hiphop, and then it all sort of fizzled out. At least in europe/uk you had the explosion of electronic music and mdma and everyone having an amazing time. American kids growing up in the late 90s were robbed.
As an American, that was a lot more going on that you didn't really hear about, but I also agree with you about electronic music. I randomly grabbed a Future Sound of London CD in the mid to late 90s, and couldn't believe what I had been missing. I have been exposed to bands like Kraftwerk, but nothing like what was going on in the UK and Europe. From there I discovered Trance music, then progressive House, and started to experiment with sequencing software like FruityLoops (now FL Studio) in the later 90s. Trip-hop then started to become popular, and it became easier to get my friends into electronic, who prior only were into 90s hip-hop (arguably some of the best ever produced).
As a 90s American teen this is completely absurd. It is literally the peak of the music industry as a whole.
The American 90s rave scene was also absolutely amazing. Big enough to have parties every Friday and Saturday but not too big to attract much undesirable people and law enforcement.
Trance originated in the 90s though it only matured after. But it was a great time for me. I'm in Europe, yes, but I heard about trance events in the US too
