"Auto tune" was one of eight Lions won by O&M London on Wednesday night at the Cannes Lions International Festival of Creativity.
Nick Darken, executive creative director, Albion, said: "This spot for Dove doesn't feel like advertising. An achingly beautiful, sparse song with an auto tune overlay. It grabs you by the earlobes and takes you on a journey every bit as powerful as a five-minute film.
"Melancholy, yet finishing with Dove trademark positive affirmation. The real beauty of this piece is that it doesn't try too hard. A production clearly created with love by people who care."
