Just so I'm contributing something useful to the conversation... this is for Mix. It can be done at home, at your kitchen table.
1) Take out your laptop. Plug it in, if you can find the adapter. Turn it on.
2) Connect your hard drive.
3) Start Virtual DJ.
4) On the right side at the bottom where it says "Automix", click that.
5) Search for the songs you want to include in your playlist and drag them to that little Automix area on the side.
6) There's a little dot in the top right of that little Automix window... click on it and then choose "Save". Save your playlist.
7) To the left of that little dot, there's a square button with a couple of arrows, like a sign on the GSP where the express lane merges back with the local lane. Click it to play your playlist.
8) Walk away.
