After dropping his "Bad Day" last week, Justin Bieber continues his stretch of somber music with Monday's release of "All Bad." The latest cut in his ongoing series of Music Mondays has the young Bieber defending himself against people that speak negatively about him to his girl. "They try to get at me / Behind your back," the 19-year-old pop star croons in the track. "Tryin’ to tell me that I’m just like the others / But I ain’t all bad." Take a listen to "All Bad" below.
