The three different screens that flash through display Aurebesh that, when translated, is revealed to be, not surprisingly, lists of songs, the machine’s playlist as it were.
Looking at the names of the songs, there are several items of interest. First, it’s amusing how easy it is to turn a line from the Star Wars movies into a convincing song title. “You know it to be true.” Is that a threat from a Dark Lord of the Sith, or a refrain from a love song? Context matters!
In addition, one of the songs in the listings is not just a KOTOR reference but an actual use of the term “KOTOR.” Whether this leaves your fourth wall shattered is up to you, but I’d say it barely counts as a crack.
Finally, it’s worth pointing out that many of the songs displayed on the jukebox are actual songs from the game’s soundtrack. They can be selected using the cantina jukeboxes and can be heard on the stronghold decoration versions as well.
On a related note, it’s not well known, but SWTOR’s wonderful soundtrack is available for download for free from swtor.com. My favorites are the tracks for Tython and Balmorra. It’s worth a listen!
