It's been quite the year for Eilish, releasing her first body of work in the form of EP dont smile at me, selling out shows and playing to packed rooms of adoring fans, as well as being the youngest nominee ever of the BBC's Sound Of poll.

Stripping away the soaring melodies and delicate idiosyncrasies of "watch", "&burn" reworks one of Eilish's best tracks to date into a darker duet more akin to the track's lyrics about literally setting an ex's car on fire.

With its guest verse from Staples, "&burn" is surely a milestone for Eilish, who is a massive hip-hop fan, having told us earlier in the year she was working "with people who I genuinely love and I’m impressed by."
