I'm assuming that all these Casinos songs are settings - maybe sequenced - for your KN7000 as distinct from audio files (e.g. MP3s)
That being the case why don't you just start new folders on your SD Card - you've got 99 folders to play with - and load and then save each song in exactly the right order for project 1 and then again for project two.
Another way is to use the 'favorites'facility on the KN7000 to have them in the order you want them.
Neither of these two approaches involves using Fred's program.
