An idea.
If any of you have registrations all over the place in various folders, for one song or another, and you want them in a particular order try the following...
Press SD Load - the big yellow one.
Select Favorite songs.
and there you have space to put a reference/link to those registrations one after the other in 40 favorites folders each with 9 'songs' without taking up any more space on your SD Card and still keeping them whereever they currently reside.
