And we are now at the capstone of the Crossbell and Erebonia arcs, and the bridge into Calvard: Trails into Reverie. Naturally, Azure Arbitrator is excluded as it was introduced in Azure, only used as a one-off, and is a bit too obvious a contender.

Because the FMC's BGM Rips often have more views on YouTube, some of you may thus recognize the songs from those more than their actual names, so I will also specify the FMC's Boss Theme #s here.
