Otherworld Musics are awesome, but several things have no otherworld equivalent, like windy days, or the underground desert. Not even towns, so you have normal "scary" night theme going on in an otherwise peaceful town at night. Which is kind of odd.
It would be nice to have some sort of options to set musics one-by-one, so you could have for example OW underground, etc. theme, but keep the town themes, windy day, etc.
