I like the past also. In fact, sometimes I watch TV sitcoms and movies specifically from the 1970s (I was born in 1976.) and the 1980s, a decade I am less in love with, but interesting, nonetheless. Anyway, I think those were simpler times and that's a big part of the appeal. I mean, why else would I watch shows like Good Times or What's Happening? I mean, they're not bust out laughing funny, but just sort of cute - and especially innocent.
Oh, and the music? Well, I've never liked music from my time that much. Note, the 90s music wasn't bad stuff, but I've always been more enthralled by 60s and 70s soul, rock etc. so definitely, my taste is music is incredibly geeky, to say the least.
