Отпишу, как я решил эту проблему. На примере всё той же музыки из транспортного олигарха. Конверт в ОГГ, размер увеличивался примерно в три раза. Закинул в выше указанную папку, потом в настройках АУДИО в игре отключил музыку эпох. Ежели нужна по эпохам, то придётся ручками править файл base_config.lua, находящийся по пути \Transport Fever\res\config\ Находим такой вот блок

В нём уже вставлены композиции из 8 и 9 папок ТГ. Остаётся только указать год начала. И при желании год окончания для данного трека.
