Event Music

If you remember, the music changes through event queues up til Figaro Castle, and Terra's theme lasts through the first time you enter the world map.

Ah yeah, it continues to play that song even on the overworld from this bit:
1CC B9:4 Temporary song override 1 (maps only)

gets set here:
CC/B051: D2 Set event bit $1E80($1CC) [$1EB9, bit 4]

I thought about the entrance event thing, but looking through other entrance events, I don't see songs anywhere, so that could turn into a big deal having to maually change the code to load music for every map.

Yes that would be a royal pain in the ass lol. I was just talking about that instance, and I wasn't aware the map/event in question was Arvis's House XD
