For a job like this, especially given that it is one instrument, I would record the song and then use an audio editor. Audacity is one that many people use, and it's free. I would apply a reduction in volume and/or a fadeout. One of the reasons this would give you more control is that editing a stereo file can be continuous / gradual (such as on a fadeout), whereas an adjustment you make in BIAB is measure-by-measure.

You could certainly do this job nicely in RealBand, a DAW software program that is supplied for free with BIAB.
