I like the song... It really took me by surprise the first time I heard it. Then I learned that it was christian inspired... I couldn't care less!
Beauty resonates with truth and that is expressed in the song as faith/love/hope no matter the content or semantic associations therein.
I also really enjoy Gregorian chants, those wailing muslim anthems to Allah, Hava nagila techno remixes, etc.
If it fits, wear it. If it rocks, kick it!
