The Logic File and the Beat

I imagined it to be some kind of disco-ish sort of one 21 10 tempo of just four to the floor. I had the lyrics and then fit those to everything else Interesting and when did the beat come? The beat was actually in the original Logic File Which was just some Logic drums that were just put in on the keyboard It sounded like I could imagine the beat being there from the beginning But it can sound like that but it doesn't mean that's what that happened.
