Who wrote the Michael buble song lost?

Answer 1

He (Michael) also talked about "Lost," which he wrote with Canadian singer/songwriter Jann Arden & Alan Chang. "It's an anthem for star-crossed lovers," Bublé explained. "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."

Answer 2

It's up to interpretation but from how I read into it, he doesnt want the relationship to end. He rather have an unsure relationship ("we'll get lost together) and stick with it until it gets better ("until the light comes shining through").
