Songfacts®:

• Flora Cash are Shpresa Lleshaj from Stockholm, Sweden and Cole Randall from Minneapolis. The pair met in 2012 on SoundCloud when Lleshaj began commenting on the tracks Randall had posted and the two connected. They began making music together in Sweden and later got married.
• This ballad from their debut album Nothing Lasts Forever (And It's Fine) brought Flora Cash to much wider attention after it was used in a viral Movistar commercial in Mexico promoting safety for young people meeting each other online. Its success earned the pair a deal with Sony imprint RCA.
• "You're Somebody Else" was written in the Stockholm apartment of Lleshaj's sister, the Swedish actress Ariana Lleshaj. Ariana and her fiancé had gone on a trip to New York, and the Flora Cash pair were looking after her apartment.
• Randall told ABC Radio that they wrote the song at a time when Lleshaj and him were going through "a little bit of a rough period."
  
  You look like yourself
  But you're somebody else
  
  Randall recalled: "It wasn't like a premeditated thought of, like, 'Oh, you're somebody else,. It just sort of organically sprung up, the melody and the riff, but it totally described how we were feeling, where you're kind of unrecognizable to yourself. And it's a little bit of a wake-up call when you feel that way."
• The song features in the "Dissection" episode of the Netflix Series Locke & Key, which premiered on February 7, 2020. It soundtracks the scene when Dodge fatally stabs Sam.
