You relies heavily on a sample of Gold Panda's single "You". The sample provides "psychedelic loops" to the track, that contains "maddening trance and haunted-house echoes" and "aural flourishes". The sound of the single has been described as a "combination of UK electro and saccharine vocals". It is set in the key of B Major.
Critical reception
In its list ofthe best songs of 2013, Pitchfork ranked "You " at number 61. It praised the Gold Panda sample, saying that it "could even make Tumblr’s weird pop elite attempt a shimmy." In its review of the album for the same magazine, Marc Hogan called the track "gorgeously bitter". The song was also said to be "vindictive and catchy" by AllMusic, who named it as a highlight of the album. Meanwhile, when reviewing True Romance, Art Ivan of Tiny Mix Tapes found the song to be "a relatively unremarkable, straight pop song that still pushes things along, especially after the self-sustaining 'Nuclear Seasons'.” When presenting the music video, Marc Hogan of Spin Magazine said that the new single "wonderfully emphasizes the pure-pop joy and street-cool swagger that lurks behind the hypnotic shadows on tracks by the likes of not only Panda, but also current Charli collaborator Clams Casino" The track appeared in many year-end lists of the best songs of 2013. Spin Magazine included the single at number 31, comparing it to Charli's previous single "I Love It" as "subtler, sharper, sleeker more vicious."
