It's not obfuscation, nor bowdlerization. It's generification, to turn it into a "plug and play" song.

...And having looked up "generification", I find it's already in use to describe the use of a brand-name product name for any similar product. Like "Kleenex" for tissue.

We'll have to invent our own word. Maybe nonspecificationary. Or there are "zipper" verses that fit into numerous songs, so maybe it's a zipper song.

And perhaps the worst lyrical mess I've ever heard was when a guy sang "Willin'". "Tucson to Tucumcari, Tehachapi to Tonapah" - what a glorious mess can be made of those place names. (When I talked to him, he just said he couldn't tell what the guy had been singing, so he made it up.)
