Fading out ME and restoring BGM in a battle

Hi, I have a specific piece of music that I want to play when the player successfully captures a Pokémon. I found the default ME that plays in the PokeBattle_Scene script, but when I replace it with my own music, it continues to play when the player returns to the overworld after the battle. How can I properly fade out my music and restore the BGM that was playing in the overworld before the battle in this script?


*EDIT: So apparently all I had to do was switch the ME music to BGM music and it faded out normally. I apologize for jumping the gun and posting the question on here before looking into the issue further.
