I couldn't help but notice in the 3.2 patch notes that every instance of the orchestrion roll for T5 calls the song "Thunder Rolls".

"Thunder Rolls" is the name of the Ramuh song on both the Before the Fall OST and From Astral to Umbral.

"Thunderer" is the actual name of the song on the ARR OST.

Pretty sure I'm not just confused as to which song it actually is, because the Faded Copy of Thunder Rolls says it's from the Ragnarok and also it's required in the recipe for Answers along with both other Binding Coil faded copies.
