It's been since 2006, but The Hollaback Girl is back with a new single off her third solo album. A Benny Blanco production provides a fun island inspired track where Gwen gets to show off her quirkiness and playfulness throughout. I don't see it getting a lot of radio play, but it's a great track to reintroduce the No Doubt singer back as a solo artist. And whenever One Republic's Ryan Tedder is behind writing the song, it's usually a guaranteed hit.
