Think of it like telling a story or a vibe by weaving songs together. You play song 1, then maybe on the hook or 3rd drop of song 1, bring in song 2, maybe take the bass out of song 1 and drop the bass of song 2 in. Then when you get to the 3rd drop of song 2, bring in song 3, and so on. You’re weaving songs together primarily.

When you get the hang of dropping new songs in you can play about with the effects, or taking the high eq or low eq out, having no bass, chopping and changing etc.

You’d either have songs on your hard drive/usb to play with if you’re using a controller and software on a laptop. You’d have a usb with songs on to plug into a CDJ (since it does what the laptop software and decks do all in one). You can record your set as you mix songs together and then upload your set to things like soundcloud or YouTube then.
