• Kane Brown penned this pop-country ballad with Matthew McGinn, Brock Berryhill and Taylor Phillips after being on the road for a long time. Though his fans were screaming his name, all Brown could think about was being back home with his girl.
  
  Heaven knows it that all I wanna do
  Is be alone with your brown eyes all tangled up
  Just holdin' onto you tonight
  
  Brown is singing about missing his fiancée Katelyn Jae (they married after the song was written). His stints on the road seem way too long when they're apart.
• Kane Brown had previously worked with all three of his co-writers, having co-penned "What Ifs" and "Heaven" with Matthew McGinn and "Good as You" with Taylor Phillips and Brock Berryhill.
• McGinn, Phillips and Berryhill accompanied Brown for some concert dates in spring 2018, and they witnessed his pain at being separated from Katelyn Jae. The experience helped them write "Homesick."
  
  "I don't know if we would've written that song if we weren't on the road, watching him miss calls and him trying to call Katelyn and then her not being able to talk," recalled McGinn to Billboard. "It was just like, 'Oh, this is their life.'"
• Kane Brown drops his own name in the lyrics, referencing a March 9, 2018 gig at Coyote Joe's in Charlotte, North Carolina.
  
  Well it says Kane Brown on a sign with a line out the door
  Sold out some little town I've never been before
  Yeah, they're screaming my name
  
  Jason Aldean did something similar on his 2016 single "Lights Come On."
  
  Here's a little something to thank y'all for showing up
  Aldean and the boys about to blow it up, haha
  
  Brown admitted to Billboard that his co-writers had to persuade him to keep his namecheck. "I just hate talking about myself as it is," he said. "So when I'm singing, 'It says Kane Brown on a sign with a line out the door,' it's weird to me. But, I mean, it makes sense."
