When I was 15 or so, a teacher asked us to bring in a song making a political statement. In class we traded and discussed them.

The kid I traded with had brought in NWA's "Fuck Tha Police." I'd brought in Tom Lehrer's "Pollution," which I thought was funny and knew by heart already; my parents had a moderately diverse collection of vinyl records that I'd listened to for years, playing them low and just sitting against the speaker.

It was an eye-opening moment -- I was a fairly solitary kid who hadn't realized how out of step I was from most of my peers.
