Al, as I understand it, in the Korg world you have a master songbook with all your songs. Then you can easily create additional custom lists that could be your "cocktail hour" playlist. No need to load anything, it's already there in your custom list. Then if you want to put the same song in another custom list "dinner hour" just follow the process Steve laid out.
What I really like is that you can make a change to the song once (say rebalance the voices) and it will be like that in any of your custom lists where it appears.
If you want to view just your songs you could call them all the "Al" genre as you create them. Then you can filter your songbook to just see songs with your genre.
Hope this helps. It's a different world, as I'm learning every day.
