Adding Music to a Bar Scene

I am editing a bar scene and have the song in the background that I want playing but it does not sound like it is playing from the speaker system of the bar, it just sounds like background music. So, I am watching an episode of a tv show right now where a guy and girl are talking in a bar. There are no sound effects (no beer bottles hitting, talking, etc- just the song playing in the background of the speaker system or jukebox of the bar). So, what type of effect do I need to put on this sound effect to make it sound like it is in the background and not just a song track in FCP...
Using FCP 6.0 and can use Soundtrack Pro though I am not too good with it yet.
thanks guys
