Songfacts®:

• This is the title track from South London Alternative Rock quartet Bastille's debut album. It was released as a digital download on August 17, 2012, peaking at #90 on the UK Singles Chart.
• Speaking to NME about the production of Bad Blood, frontman Dan Smith said: "We basically made the album in a studio the size of a cupboard, so it was one extreme to the other. Producing the record, I wanted to off-set epic sounding instrumentation with lyrics that combine intimate stories or conversation. The contrast was something that appealed to me."
  
  He added: "I wanted each to be its own story with its own atmosphere which brings in different sounds and elements of production, incorporating aspects of the different genres and styles that I love; Hip hop, indie, pop and folk. Film soundtracks can be broad and varied but tied together by the film itself - and I hope the album will be something like that, but held together by my voice and my songwriting, each song a scene or part of a bigger picture. Some of the album is about stepping back and looking at what kind of person you've become. It's that dawning realisation that everything has piled up on top of you and it's up to you, as an adult, to sort yourself out."
• Smith told The Sun regarding this song: "When we wrote 'Bad Blood,' I was listening to a lot of Gorillaz and film scores with an emphasis on strings."
