The LP-16 has no remote control option for song selection.
But it has a random playback mode if that is what you need.
The next song selection can be done from the main screen by pushing the up/down key or you can use the browser for selecting the song from the drive.
The playlist feature can be also used if you prepare the list on your PC then during the show you load the playlist (with the pre-definied song order) but you can insert/change the next song during the playback using the browser function.
It may worth to conciser to take a look for the uTrack24 as well, because it has iPad/Android/PC/OSX remote option which helps for the quick access to the song selection.
