>For instance i know virtually nobody into 80s music, but 90s r&b and hip-hop are reliable favorites.

If you've grown in the 90s then that is probably skewed (from nostalgia etc), but I'm not talking about that (observations between personal friends etc of the same generation).

I'm talking about later generations insisting/obsessing on some previous decades (that they weren't even alive or old enough to experience). So statistically speaking (based on releases that "recreate" that sound, shows, movies and books about the era, re-releases, fashion, etc).
