Justin Bieber released a new song, "Hold Tight," tonight. The song finds Bieber once more ruminating on love over smooth R&B sounding production. Bieber flexes his vocal chops as he talks describes the addictive power of a girl's lips. "Hold Tight" is the third installment of Bieber's Music Monday series, and is in the same lovesick vein of the other two releases. Bieber has more of these "journals" every week until the release of his Believe movie in December. Also on the horizon is the full version of his collaboration with Tyga, "Wait A Minute." That will come out Tuesday.
