Big boy Bieber continues his movie-promoting, between-albums #MusicMondays series with "All That Matters," a bluesy, lurching slow jam. About the song, her wrote: "Love is all that matters. But the void you feel when that love goes away is gut-wrenching. I worked so hard on this song in the studio - trying to put that feeling into music was extremely important to me." Sounds like he's trying hard to nail a singing-verging-on-rapping flow, and getting there.
