Lana wrote this song after BBC Radio 1 started playing her first single "Video Games". She told The Sun: "I was grateful that the song being on the radio brought some old friends back into my life — especially one person."
Lana penned the lyrics and melody for the majority of the Born To Die tracks as she walked round Manhattan. She then took them to her producer, Justin Parker, who helped her put the chords underneath. However, this track was different as she improvised the words to Parker's music. She told The Sun: "With the track 'Radio,' Justin just held down long keys. Sometimes what I ask my producers to do is just hold down long extended, melancholic notes and I end up just freestyling over them."
