Biab should not mess with a melody, it will play it exactly as recorded. As for jazzing up the backing tracks, that depends on the style and there's a checkbox for "jazz down the chords". I'm at work and can't tell you exactly where that is but it's in the help file. Try some simple rock or country styles, those usually keep things fairly basic. There's also a whole collection of gospel styles but those tend to be complex full band arrangements so that may be not what you're looking for.
