• The soundtrack tends to reprise different arrangements of the same few songs as source music, especially "Santa's Watching" and "Christmas Fever" - it can get a bit repetitive, but is actually true to how ubiquitous Christmas songs can be. If you tune to a radio station that goes "all Christmas" during that time of the year, you'll notice it's mostly different cover versions of the same few songs. Apparently, "Santa's Watching" is just a really popular Christmas standard in-universe.
