Billboards in cities from Reykjavík, Iceland, to New York City, Atlanta and Los Angeles are teasing new cover art that simply shows the word "Swag" in gray on a black background. A parental advisory label for "explicit content" is in the lower right corner. On the afternoon of Thursday, July 10, the 31-year-old posted a flurry of photos and videos of the marketing campaign on Instagram, with some of the images depicting a 20-song track list that includes titles like "Dadz Love," "Go Baby," "Swag," "Zuma House" and "Forgiveness." #justinbieber #albumrelease #swagjustinbieber
