• Smart people can do very stupid things if they're letting the wrong organ make the decisions. Shawn Mullins has a very stupid heart, and unfortunately, that's what guides him, always playing him for a fool.
  
  It's that kind of sentiment we can all relate to on some level, and there are no shortage of songs about love clouding our judgment, but Mullins felt this more acutely than most. His first marriage ended in the '90s when life as a touring musician caused a fissure, leading to infidelity (on her part). He married again later in the decade and the couple had a son in 2009, but they split up a year later. Undeterred, Mullins married again a short time later, and that union quickly ended in divorce.
  
  These tribulations led to many of the songs on his 2015 album My Stupid Heart, including the title track, where he takes himself to task for his folly. He wrote the song while sitting on his porch thinking about how he needs to own up to these mistakes, but how much easier it would be to just blame it on his heart, so that's what he did.
• Mullins wrote this song with his longtime collaborator Chuck Cannon; the album was produced by Cannon's wife, Lari White. Cannon, who had co-written the John Michael Montgomery country hit "I Love The Way You Love Me," sought out Mullins when he heard his 1998 song "Lullaby."
• Mullins kept listening to his heart and letting it make the calls. A few years after this song was released, he entered into his fourth marriage. "If I fall in love with someone, I tend to want to marry them," he told Songfacts.
