Beyoncé professes her unwavering love to her man on “1+1,” the opening track off her fourth album 4 (June 28). The songbird lets her voice soar on the power ballad. “Make love to me when my days look low/ Pull me in close and don’t let me go,” she commands over the guitar-dripped melody. If “Run the World (Girls)” wasn’t your thing, this should do the trick.
