"Lost" by Michael Buble

A sentimental, self-penned ballad “Lost,” co-written with Chang and Canadian singer-songwriter Jann Arden. “It’s an anthem for star-crossed lovers,” Bublé says. “Sometimes relationships don’t work out because love isn’t enough, but that doesn’t mean you have to discard the person. There is a way to end a relationship and still be there when they need you. That’s basically what it’s about.”
