Blackmore's Night has a crapload of songs that make for excellent background music for Dominions 3.

For Hinnom, Scarecrow by Tobias Sammett's Avantasia makes for an awesome theme song. A part:

...
So you're an angel meant to walk down here
And you say it's all divine
And you don't play by all those temporal rules
You watch the world begin to die...
...

If that doesn't scream Lord of Civilization to you, I wonder what would...
