Now I haven't done Coils yet so I don't know for sure, but isn't the final boss for turn 9 just a
rehash of battle on the Rivenroad against Nael van Darnus from version 1.0?


In which case the battle music is simply tracks returning from version 1.0, namely Nobuo Uematsu's Tempest and Masayoshi Soken's Rise of the White Raven. I agree they're awesome tracks though, although they're not exactly 'new' music. If I'm wrong though, then ignore my ramblings.
