現(xiàn)在這個和我分析的有比較大的出入，以下為我于6月25日寫的分析：

大概整理了一下，這里采用街霸式命名（角色+具體音樂），和官方給出的音樂名稱有出入，等6月30號對編號：

ARMS Grand Prix Final Battle [ARMS] (Original)
Victory! Min Min (Ultimate)
其中勝利音效應該是ZZ03。
估計ARMS的編號是AR或者AM，由于本體沒有收錄任何ARMS音樂，編號不至于跟著R走。
音樂的文件排列順序差不多應該是這樣，按照角色菜單排列順序給出來的，且不會留空，游戲中收錄的音樂順序不出意外和前兩天櫻井演示的一樣。
目前我不知道那個Final Battle是什么玩意，因為會長有兩段音樂，個人估計是會長的第二階段音樂，不過在SmashWiki查到的資料說是博士二段，我也不知道這個指代的是什么，可能是更新博士之后不怎么打這個游戲的原因，沒印象。

這樣看來，ARMS排布順序應該如下：

主題曲→參戰(zhàn)角色場地曲→常規(guī)角色場地曲（以菜單順序排列）→Boss角色場地曲（會長）→特殊模式音樂（頭套）→Boss二段音樂。

其中主題曲中包含了會長的旋律。

目前大亂斗原音頻文件總時間長度為61h55m4.328s，游戲中音樂播放器總時長為33h41m46s。
