Don't restrict yourself to just Biab files, look for midi files too. Biab is pretty good at extracting the chords from a midi file and laying the whole song out for you. That chord wizard is not perfect, you usually have to make some corrections but it's a good start and saves a lot of time because you at least have the roadmap done. The same can be said about the Audio Chord Wizard. If all else fails, get a recording of the song in question and let the ACW have a run at it. Again, not perfect but still useful because even if the chords are all wrong you still have the song layout as a start. Rharv has an excellent tutorial in the Tips and Tricks forum about using the ACW.
