In the new song, which follows up 'Heartbreaker', the Canadian star sings about how much he needs his lady.
Justin Bieber drops "All That Matters" on the second week of his 10-week "Music Mondays" series. The acoustic ballad features the 19-year-old pop star singing about being so much in love with his special lady.
Bieber can be heard telling his girl that he's nothing without her. "You're all that matters to me/ Yeah yeah, ain't worry about nobody else/ If it ain't you, I ain't myself/ You make me complete/ You're all that matters to me," he croons. "What's a king bed without a queen/ There ain't no 'I' in team."
Earlier this month, Bieber announced "Music Mondays", an event which allows him to release a new song every Monday at midnight for ten weeks. Last week, he kicked off the first week with long-awaited new single called "Heartbreaker".
"It's a song for people going through heartbreak - like I was when I wrote it," Bieber later said of the song, which is presumably about ex-girlfriend Selena Gomez. "It means so much to me to be able to share what I was, and still am going through, with my fans. I'm very proud of this song and I hope it gives my fans some insight into my heart."
