I sometimes find when loading new games, while the music from a previous game is playing, the music either keeps playing once the new game save is used, or there is a double-music effect of two tracks playing at once.
I haven’t a clue on how to easily prevent this from happening.

<<createplaylist "bgm_GameLibraryD">>
<<track "LDA" volume 0.1>>
<<track "Cosmic" volume 0.1>>

In Passage
<<playlist "bgm_GameLibraryD" play>>
Obviously I have lots more music playlists in the game, but those are just an example.
