Jason Mraz is living full spiral. It’s not full circle, exactly, because he’s changed and his experiences have changed, but on his eighth album, Mystical Magical Rhythmical Radical Ride, the musician has found himself returning to a familiar junction in space. The new songs, which are unabashedly pop, see Mraz reuniting with numerous collaborators, including Los Angeles band Raining Jane and producer Martin Terefe, who helmed 2008’s We Sing. We Dance. We Steal Things. In fact, as Mraz looked at the number eight, he instead saw an infinity sign.
