I’m clearly not understanding the issue here, because every chord is important and BIAB does follow a standard. It’s just that there are several standards and they can differ.

The issue here is that AI cannot provide a complete list of all chords ,which are possible in BIAB, because different notation systems are used in the chord sheet.
The only thing you can do is have AI compile a list of all possible chord types and enter this into BIAB.

Of course, some chords will be left out of the progression, as I have already experienced.
Then you have to try to get them to work manually in BIAB.

It's just a test.
