(empo-tymshft) (empo-tuulwey) When terms lose their meaning

I was listening to Rage Against the Machine's "Revolver" when I began musing on the Beatles album of the same title. And it suddenly occurred to me that someone who was just introduced to the Beatles album today might not realize the humor behind the title.

Yes, CDs (and cassettes) revolve just like old vinyl LPs did, but CDs revolve inside a closed case, so you don't necessarily notice the revolving. With an LP, it was very obvious that the record was revolving.

And, of course, when you're talking about digital downloads, the concept of revolving does not apply.
