Tehrene Firman of Teen Vogue called the song "today's new '80s-inspired".[9]
Bradley Stern of Idolator wrote that "'Right when I think I finally got you figured out, you turn around and blow my mind,' the crooner starts above the song's kicky pulse, giving just a little of that Prince funkiness in the process. Things get even sexier as he heads into the chorus. Sounds like a real smash to us".[10]

In an interview with The Advocate Nick said that he was lucky to work with the Producer. At the same day of the announcement the remix appeared on Soundcloud.[20] Mike Wass of Idolator said that the Dave Aude Remix is a fun track with a weird (in a good way) Harold Faltermeyer vibe.[21]
