As a kid I rarely listened to anything, these days I put on Hitchhiker’s Guide to the Galaxy radio show, just go bacl to the start I’ve heard up to the third phase often but not the further ones as much. In the more recent past it may have been a Harry Potter (UK) book or again Hitchhiker’s Guide to the Galaxy voiced by Stephen Fry. Guess that’s a lot of UK stuff considering I’m Canadian, but Fry has such a nice voice to drift off to.
Not saying wrong but that movie came out in '99, so I think a retro of the 90s would be closer to mid to early 90s since there’s that bleed over to the early '00 decade. Of course I’m older so maybe that part would be included, just more considered it 00s era.
Since I didn’t comment otherwise I’ll mention Xtreme sports, frosted hair colours, and some neon bleed over (though not cyberpunk levels) from the 80s for a 90s retro.
