Critical reception
The song is described as an "irrefutably stylistic party anthem track that is sure to make a statement on the charts". Kat Bein of Billboard wrote that the song has "straightforward melodies, easy beats, and a good, clear vocal", and felt that there is "nothing flashy about this future bass drop". Jeffrey Yau of Your EDM thinks that the track "seemingly strikes the perfect balance between summer festival jam and infectious radio hit that'll easily stick in your head with its sugary-sweet lyrics and very simple chorus", "all three artists' sounds and styles" are well blended, and "the melodies in the track are memorable enough to keep the tune in your head for a full day or more". Erik of EDM Sauce wrote that the song "is not something groundbreaking" but "is honestly pretty good" and is "catchy and fun". He described the vocals as "electrifying" and the drop as "minimalist".

Music video
The music video was released on 21 August 2017. It was set in Ibiza and directed by Phillip R Lopez. The video depicts the Ibiza's landscapes with dancers. Kiiara can be seen wandering outdoors on cobble-stone city streets of Ibiza Town with Dimitri Vegas & Like Mike staying on the top of the stone and watching over the town before leaving and walking on place with colored smoke in the night at the end of the video.
