"Cool party-styled boombox! Doesn't play any auctual music though..."
The Party Boombox is a purely decorative item. During Alpha, the boombox played music on a local script, but it didn't work, so it was scrapped. The Berezaa Games Radio is it's successor, though not having a physical form, and costs uC to use.
Despite its description of not playing any music, berezaa has proposed to give the Party Boombox the function of allowing the player to access the Berezaa Games Radio when they have it down on their base.
