The post below on spiritual music rising during times of increasing violence serves to correct the lame spiel we always hear about how materialistic and bla bla bla the culture became sometime during the 1970s and really soaring during the 1980s.
At the same time, as hinted at with the "1999" reference, they did do celebration-of-the-flesh music a lot better too -- hell, in all media. When you perceive the order of the universe crumbling all around, you've got those two options.
Here's a #1 hit from 1978 that unfortunately has been eclipsed by a lot of the cornier-sounding disco music that topped the charts (although disco overall is fun, especially Chic). Even among a broad audience of people who weren't even alive then, or were children, it seems like Blondie and The Ramones have gotten their due, while The Bee Gees have fallen more by the wayside. So maybe some of the lesser known '70s classic rock hits will find a new following too.
Nothing wrong with the artier rock of Talking Heads from that era, but music plays so many more roles than tickling the brain. Sometimes you just want to silence the self-conscious part of your mind and take in a sky-opening let's-go-do-it song. You won't find that among the spotlight-soaking skanks of the past 15 to 20 years.
