Justin Bieber's 'All That Matters' Debuts As Latest 'Music Mondays' Installment

Justin Bieber continued his ongoing "Music Mondays" series with the release of a new single called "All That Matters." The 19-year-old pop star is debuting a new song each week (last week he debuted "Heartbreaker"), in the lead up to his fourth studio album. Bieber takes a mellow approach with "All That Matters," crooning about his love with lyrics like, "Yeah, yeah, what’s a king bed without a queen / There ain’t no 'I' in team / You make me complete / You’re all that matters to me."
