I regenerated the song many times and most of the time I got something like this:

Measure 20 = G# - The notes that are being played from the highest to the lowest note are G#-D-C#-G#-G#

Measure 21 = C#m - The notes that are being played from the highest to the lowest note are E-C#-G#-C#

As you can see the only difference between the two chords is two notes; The G# chord has a D while the C#m has an E.

Personally I heard that difference in each generation even though sometimes some notes were eliminated, usually in the C#m. You might want to regenerate a few times until you get what you want to hear.

Why is it that doctors call what they do 'practice'?
If flying is so safe, why do they call the airport, the terminal?
