I was a disc jockey for 18 years and I can't tell you how many phone calls I've gotten during my shift which went like this:
Caller: Hey, I want you to play that new song for me and my girl.
Me: Which song is that, my man?
Caller: Aw s#*t, I can't think of the name of it, but you play it all the time.
Me: Who sings it?
Caller: That dude...what's his name...(off)HEY, BABE, WHO SINGS THAT SONG? (pause) She don't know either.
Me: Do you remember any of the words?
Caller: (Haw haw)...no.
Me: Can you hum a little bit of it?
Caller: F@#k no, I ain't gonna hum it! Are you gonna play it or not?
Me: Coming right up! Thanks for listening to Rock 98!
Sometimes, they'd actually call back later and thank you for playing it.
