Even in his more pensive moments, Andy Grammer is walking on the bright side of life on his sixth album of upbeat, heartfelt pop songs. “All I Want Is You” turns his frustration over being away from his family into fodder for a shout-along anthem, while “Love Showed Up” explains how he “had to lose it all to see how much I have.” The “honey, I’m good” charisma that helped catapult Grammer to pop stardom in the early 2010s is on display throughout Big Stupid Heart, and his charm and sharp songwriting make it hard to not smile along.
