Thanks, Brian. The radio button method seemed to hold some promise, but there are a couple of issues that will thwart what I'm trying to do. Giving it a test run, I started my first pre-fab playlist, then went into Playing Now and saved it to the first radio button. I shuffled the songs, then did an Update Order by right-clicking on Playing Now. But when I start a different playlist and then go to the radio button with my earlier playlist, the order has reverted back to how it was when I loaded it (before my shuffle). And one more thing: when I hit the radio button, it starts the playlist from the top.
To clarify, here's what I want to do. I'm at a day-long festival. Generally, it's country music in the morning and pop/oldies in the afternoon. Mixed in between are performance tracks (vocalists, dance) and other stuff (cake walks, kids music, etc). I want a separate playlist for each category that doesn't revert to the original lists (i.e. remembers changes). Now let's say someone requests "Never Coming' Down," which is near the bottom of the country playlist. No problem, I drag it up to the top of the country tab and play it at 9:30. When I change tabs (or playlists) to performance tracks (because someone tries to sing), when I go back to the country tab, I want "Never Coming' Down" where I left it at the top of the playlist so I can restart the playlist with the next song below it and don't have to worry about it playing again in an hour because it's still where it started in the playlist. Is that understandable?
So I would really like multiple playlists that are unchanged when I switch between them.
Thanks for your help!
