Once again just my opinion but if you have used registrations successfully on any PSR or Yamaha arranger for gigs, the Playlist feature brings it up quite a few notches. I liked Music Finder and have used it for live play at gigs but as Randy has mentioned it did lack some flexibility.

Sorry to have to say if anyone thinks Playlist can’t hold a candle to Kong’s Songbook they have not mastered the use of Playlists on the SX900. As I’ve already mentioned there is a learning curve. What I like about Playlist is my registrations can call up the corresponding lead sheet/ lyrics on my iPad Pro and vice versa. I also like Songbook on my Pa4x that it can call up leadsheets/lyrics on my Android tablet. Both Songbook and Playlist do the job equally well in my eyes.
