The 80s is big now (or just before now, we’re creeping into the 90s tbf) because nostalgia cycles work in 30 year loops… roughly the time it takes for people who were teens/formative early adults in any given era to become taste making arbiters in adulthood (I.e. the people in charge of making, producing and commissioning shit) so, like, usually people in their 40s & 50s… Also a time when you start pining for your youth as you’re probably getting divorced and your kids are hitting the same age you were when you remember all the cozy lovely things you do now about your childhood.
You can like any particular eras aesthetic for any number of reasons, but the reason they become huge important cultural touchstones years later (like the 50s did in the 80s for example, with Happy Days, Back to the Future, Peggy Sue got Married, Greece, lots of remakes of 50s B Movies etc) is because of that… not because the music you personally like was actually the most amazing and wonderful decade of creative endeavour ever.
Every decade will get this treatment at some point. We’re about to have it with the 90s, which in turn had it with the 60s/early 70s (why guitar music became really big again)
EDIT: oh, you’ve stopped having that discussion. Well…Good. Ha! let that be a lesson to ya!
