Honestly, I've been laughing a lot lately due to finding appropriate music from the player's perspective for this AP. Almost all of it is Irish folk or Irish Punk/Rock.
The "Boy's of Belfast," parodied to be the Boys of Westcrown. This is great for the resistance.
Flogging Molly's "Devil's Dance Floor" is a great interlude song for the Sixfold Trial play.
For instrumentals, the "The blood of Cuchulainn" is a great opener...
So, what other songs or music would be appropriate, given any genre is good?
I went with Italian light opera; lots of Verdi and Rossini. Works especially well for the second mod.
Try La Forza del Destino. There are some good clips on You Tube even.
