Tracks 13 and 14 are Japan bonus tracks.
All I Need is listed as track 14 on the back cover, however, it is actually track 13 on the disc. The back cover skips over the number 13 and instead goes from 12 straight to 14.
The back cover also states that Deck The Halls (I Hate Christmas) is the 15th track, when it is 14 on the disc.
As for track 15, it is just 4 seconds of complete silence. In the Japanese lyric booklet, the silence track is listed as track 16 (a track that doesn’t exist) and is titled (Hidden Track), despite the fact that it is only silence.
What’s odd is that there actually is a hidden track at the end of Deck The Halls (I Hate Christmas), however, it is part of the same track and is not separated from the main song. About 5 minutes after the song ends, a hidden prank call to Sony Records is played. The 4 second silence track is most likely a glitch that occurred during manufacturing.
