"And now you find yourself in '82, The disco hotspots hold the charm for you." --Heat of the Moment There are a lot of songs that remain in rotation on the radio to this day, despite the fact that their lyrics are firmly specific to the time and audience for which they were created. Such as the line "Watergate does not bother me" from "Sweet Home Alabama." The ones I find most curious are ones that are explicitly about nostalgia for a certain time period, and became popular pretty much because everybody listening remembered it. Then they remained on the radio because a different generation grew up hearing THAT song and considers the song itself nostalgic. "Old Time Rock and Roll" is a big one here. It's about the superiority of fifties rock, which barely gets any airplay nowadays unless you get lucky on the AM dial. The song's protagonist was a teenager in the fifties and hates that "modern disco." Odds are good nobody hearing the song now is "reminiscing about the days of old." Then the song became synonymous with the most famous scene in 1983's Risky Business, and gained a completely different reason for being. Now it's a song associated with the 80's, despite clearly trashing that era and singing the praises of tunes thirty years older than that.
