I've talked about how I listen to NPR (with a Tango radio playing simultaneously).
I heard a 2-minute novelty song on WFMU today which refers to listening to two radio stations simultaneously.
It's called Jazz versus Rock & Roll (yeah, that's the title) by Woody Byrd. I'm guessing it's a product of the 50's. It's on Jaro records.
The singer tells how he and his girlfriend disagree on music - he's all-jazz and she's all-rock. Little snippets in the music illustrate. Their conflict escalates until both are always blasting their own stations. You can hear this in the tune. (It's only slightly Cageian.)
As in any good song, the conflict is resolved at the end. I won't say how. My Grandmother would have approved.
Go to Todd-o-phonic Todd's archive page at WFMU , play the show from October 22, 2005. Jazz vs. Rock & Roll starts at 29 minutes and 35 seconds.
