"Goron Ki Na Kalon Ki Duniya Hai Dilwalon Ki" (English translation: Not to fair-skinned people or dark-skinned people, the world belongs to those with good hearts)
Don't think I'd ever heard this before.
The vocals are so odd, one minute he's out of key or something and the next its her turn.
Yet they can both clearly sing well
I can only assume it's purposeful, but it's still weird as heck.
The music itself is great tho.
