You select a file and press play. You could also press F9 .. F12 to
start/stop the decks. Or you own a studio surface which sends joystick
button press/release events.

If you have a USB joystick, simply connect it. Press Button 1, and it
plays deck 1, release button 1, and it stops. Of course, you can also
press Buttons 1-4 simultaneously to have all four decks playing at the
same time. ;)

Selecting a new file while one is playing queues the new file. Press
stop or wait for the current one to finish to actually play it. (it's a
safety for radio stations, so they're not accidentally stopping the
current playback).

Same for stop: program only quits if you stop all four decks and then
press Ctrl+q. Well, the window-close button is a shortcut, but it
wouldn't be visible in fullscreen mode.
