• The Vamps told MTV UK that this song had a big influence on the sound of their debut album. "We really enjoyed making 'Can We Dance,' but with 'Wild Heart' we kind of experimented more with musical genre in the sense that we added a banjo and mandolin," James revealed. "We like to try and push ourselves into directions to try new things really and we've gone for more of a folky vibe so we hope people like it. We like to think it's a feel good song I guess."
  
  Bradley added: "Wild Heart has kind of influenced the rest of the album sound almost just because it was such a key song for us."
