• James Blunt has been married to the mother of his two sons, Sofia Wellesley, since 2014. "Beside You" is a rock ballad where he sings of finding love and happiness after a long period of searching. "It's a bit of a celebration," Blunt said. "An upbeat banger about finally being with the one you've been searching for your whole life."
• Blunt uses religious terminology throughout the song. He starts by explaining he had relationships with several girls but none of them lasted.
  
  Oh, Lord, here I go
  I get the highs, but why the lows?
  Set me up with all these souls
  And I watch them fall like dominoes
  
  Now he's met his soulmate, the woman he wants to spend the rest of his life with.
  
  I hope there's a song that God only knows
  And it's keeping me dancing
  Nobody here knows how the melody goes
  But it's keeping me dancing beside you
