Slip's Music Database: MapleStory BGM & OST Collection

I noticed this isnt listened either. I found it under the BgmUI folder called Title_Frozen. Was there a event based on the disney movie Frozen and this was a special login music for it?

I cannot remember if the music was used or not but indeed there was a Frozen event.
