Radio (also known as “Cinnamon”) is a song written by Del Rey and Justin Parker.

Talking about the song in an interview in 2012, Lana said

People always said ‘oh well people will come out of the woodwork and change their mind about you, they’ll start to like you because you’re on the radio’ and it is true, but I don’t mind, cause I’d rather have people be nice to me, so I liked it. I don’t really care why people are nice to me, I just like it when it’s easier.

Del Rey went on to explain when she wrote Radio by stating that she wrote it when a guy she used to know came back into her life,

so I was like now my life is sweet like cinnamon, cause he came back.
