JUKEBOXW.SI

Not to be confused with JUKEBOX.SI

JUKEBOXW.SI is an Interleaf File that contains world assets used when you play the jukebox next to the pizzeria. Its name is presumably short for "Jukebox World". Confusingly, it does not actually contain any music or sounds whatsoever, as all of LEGO Island's music - and therefore the music played in this section of the game - is stored in JUKEBOX.SI instead.
