At some point in the middle of Jaina's weekly planning/taking care of things time, "Feliz Navidad" started playing from somewhere. In June. It'd taken a good five minutes of hinting for the source- Jaina didn't have a ton of patience- before she decided she was just over it.

So anyone passing by her office would find Jaina sitting in the hall outside her office with her datapad in front of her and the door closed. You'd even probably still hear the music.
