I have a playlist of songs for Iron Gods. However, I am at a loss for songs for The Choking Tower book. Does anyone have any suggestions for non-score songs?
Iadenveigh is your basic farming town devoted to Erastil, so something more rustic and rural would be appropriate.
Perhaps the theme for Driftwood in Divinity 2 would suit your purposes there:

Given the Aurora is a crashed ship, obviously something more sci-fi would be appropriate, whatever you used for the haunted ship in Scrapwall would work; however, I might suggest using something like the Phazon Mines theme from Metroid Prime:

The Choking Tower is your standard wizard tower filled with undead, but with some machine elements tossed in. There are a couple tracks from CRPG Kingmaker that work great for this, City of Hollow Eyes and the more aptly named Tomb of the Iron God's Champion

For additional suggestions regarding battle music, I've been using Xenoblade Chronicles battle music, since that game is all about fighting robotic enemies, as well as some other tracks:
