Unlike Fire Emblem Heroes, Fire Emblem Shadows credits seem to be updated quite regularly! The Battle Music Arrangement section was updated. Kondoh has yet to be credited for the Genealogy of the Holy War arrangement since it's not yet in the game. Also Sekigawa returning back on the franchise with
this banger rock-heavy arrangement is really nice! The credits state he did arrangement for "Path of Radiance" but the medley also feature quite heavily "Eternal Bond" from Fire Emblem Radiant Dawn lol (to be fair it's heavily associated with Ike so it's completely understandable).
