There's little question that Justin Bieber's surprise-release of "Swag," his first album in four years, on July 10 was one of the biggest bombshells of the year in the music world, and its huge first-week numbers reflect that.

Scott's album lands at the summit with 232,000 units this past week; Bieber’s ‘Swag’ logs nearly 200 million streams.

Justin's behavior in the months leading up to 'Swag,' including public arguments and highly criticized social media posts, has fueled concerns among close friends. One insider said, “He has mood swings — he’s kind of an extreme personality in that sense.”
