David Kelzenberg said, "I have come to the conclusion that for
whatever reason the style 125 arrangements are often the most
interesting.  ...  Has anyone else noticed this? "

I have transposed quite a number of the MIDI files on the player
piano roll scan site from the 125 and 150 scales to the Carl Frei
20-note scale.  I noticed that overall I have been happier with the
125 tunes, and have used more of them, although I had not made a
head-to-head comparison study.  There seem to be many more "classics"
in the 125 list which are still worth playing, and more "short-term
hits" in the 150 list worthy of being forgotten.
