The extraction of chords from midi files is not that great when you're talking about jazz standards because those chords are complex. Simpler styles like country, rock, blues are easy for the program, jazz isn't. Remember, chord info is not part of the midi standard so Biab is making educated guesses as to what the chords are and many times it guesses wrong.

The best way to compile a library of jazz standard Biab songs is to find them somewhere in the internet whether free or buying them from Norton Music.
