'Loca People' has received a mixed reception from musical critics. Robert Copsey and Lewis Corner of Digital Spy were critical of the song, giving it one star of a possible five. In reference to the song's lyrics, the review read: "What the f**k?!" [sic] In contrast, Samantha McCallum of Maxumi Magazine provided a positive review of the track, stating it "will continue to carry the party on". "It seems as though the purpose of the song is to become a party ritual," McCallum commented. "If so, it works."
The Torre Agbar in Barcelona featured in a postcard in the music video of Loca People where it was described in the subtitles as 'Giant Dildo'.
