365 (Zedd and Katy Perry song)

In August 2018, Zedd was the opening act of Perry's Witness: The Tour in Australia and New Zealand. While on tour, the pair worked together on new music, although Zedd was unsure at the time if the collaboration would result in any material. In January 2019, there were rumors about the upcoming release of the song, which was eventually leaked. It was later registered with Universal Music Publishing Group in February, and the song then appeared registered on Shazam before being removed and re-added again. On 13 February, Zedd and Perry began sending emojis to each other on Twitter before Zedd shared the trailer for the video. ==Critical reception==

Brittany Spanos from Rolling Stone complimented the track and described it as a "breezy, hypnotic love song". Winston Cook-Wilson, in his review for Spin, wrote that "365" was "a featherweight piece of pop-house that luckily does not sound like every other Zedd song the producer has released in recent memory". Michael Love of Paper praised "365", calling it "a pretty solid pop tune from Zedd and Perry, which of course, is what also helps you stay till the end." According to Mike Nied from Idolator, it had been "perfectly tailored for a Valentine's Day release" with its "sugary sweet lyrics". ==Chart performance==

In the US, "365" debuted and peaked at number 86 on the Billboard Hot 100, spending a single week on the chart. Additionally, the song reached number one in Israel and Bulgaria, as well as the top ten in Lebanon, Netherlands, Argentina (Anglo Airplay), United States (Hot Dance/Electronic Songs), Australia (Dance), Mexico (Airplay), Netherlands and Lithuania. It also reached the top 20 in Estonia, Hungary, US Dance Club Songs and Greece, and top 40 in Australia, the United Kingdom, Scotland, Romania, Slovakia, Slovenia and Ireland. ==Music video==

The music video, directed by Warren Fu, was released alongside the song on 14 February. It depicts Perry as a robot and Zedd as a human test subject, where an experiment is conducted to test the two living together. The robot starts falling in love with him, but he does not love her back and distances himself from her. She begins to malfunction because of her heartbreak and is deprogrammed. Sam Moore of NME described the video as "sci-fi-indebted". Idolators Mike Nied praised it as "essential viewing". Conversely, Winston Cook-Wilson of Spin stated that "Mostly, one just wonders if the money could have been spent better." ==Track listing==
