Another noncommittal variation of the "I'll see what I can do" response DJs often gave when I requested songs as a kid: "We're working on it."
As a kid, I didn't question that response, but I still thought, "Working on it? Is heavy machinery involved? Why doesn't the DJ just get the song out of the station's library and play it when there's a spot available on the playlist?"
The usual answer: There were no available spots on the playlist, as that day's music had already been predetermined.
