Tre Principesse includes at least one if not more gospel songs on each CD and in fact, gospel and religious music is what the string group "Spirited Strings" specializes in. 

- Amazing Grace 
- How Great Thou Art 
- Three Wooden Crosses 
- Bridge Over Troubled Water (oftentimes this is considered to be religious.) 
- Morning Has Broken 
- The Prayer (Andrea Bocelli & Celine Dion) 
- etc.
