* - WAVE chunk has N subsongs
* - NAME chunk may define M names but usually doesn't match with subsongs (may be less or more)
* - LVRN may define some state and LVAR its possible values (battle_state=bgm_battle_start/win/intro)
* - TRNS also has names based on possible transition
* - final WAVE seem to depend on NAME (event?) + state=value, similar to Wwise
