 This was probably pretty lame , but in those days putting any word in front of the noun " city " to sort of emphasize the totality and pervasiveness of it was just a way of talking people had . If someone suggested going to a store but you had gotten a bad deal there you might say , " Oh no , that place is ' rip off city ' . " Calling an LP Radio City would be kind of wishful thinking . I mean we hoped it would be played on the radio a lot , making it " radio city " . Of course it didn 't pan out that way ...
