I started to use Musicfinder exclusively lately:

1. First thing I did was use YamahaRegManager to change all my registrations to a Musicfinder file in one single batch processs.
2. Next I included the key in which the song to be played at the end of each song name entry.
3. Then I rename the styles to the song name and store all these styles in the same folder.
4. All other settings are stored in the OTS settings of the style i.e. volume levels, all voices, nultipad etc.

The above procedure really works GREAT for me!
