Hey Gary, I believe if you had the SX-900 for a few days, you would find the Playlist on a PSR-SX-900 to be a more efficient way of accessing registration song sets. You can easily have multiple playlists readily available, with almost an unlimited number of songs for whatever gig your're playing. I rarely used MFD, but find myself using Playlist often.
But hey, I'm just a Jedi, and you sir, are Obi Wan, the Jedi master
