I would recommend downloading the trial version of virtual dj, which you can use as long as you want (though you can’t use a controller with it) It’s really good if you want to learn basic stuff, beat matching and whatnot.
Even if you don’t plan on mixing in any way, i recommend it just for playing music, when one song is fading out, you can start the next one. It gives the whole thing a much smoother feel.
That’s how I started off, just a basic summer camp DJ (which I still do, but with a little more experience), and I just kept learning little tricks to make everything sound better and more fun, and eventually, BAMMM!!! DJ.
But whatever you do, just have fun with it! Good luck!
