Fresh feels better than nostalgia, but things haven't been fresh for a while, so we fall back to nostalgia.
Part of what makes the '80s and '90s nostalgic in the first place, was how new, exciting, and optimistic things felt. People in the '90s weren't even nostalgic over the '80s, which already seemed dated in comparison, cuz the wheel kept on turning smoothly.
Love or hate Skrillex and modern EDM, but it at least felt fresh and exciting around 2010. Now everything just seems like a curated homage or throwback to something else. As nice as it is to see some styles come back, it's also bittersweet, and not necessarily a substitute for innovation.
I think I'm saying; a style is more than the sum of its parts. Borrow from the past, sure, just don't get stuck there. Pick up at a good point where things left off, and keep the underlying intent and spirit alive, instead of a retrospective checklist.
