Zedd, Katy Perry, and "365": Recording History and Chart Performance

The collaboration between Zedd and Katy Perry on "365" represented one of the more intriguing cross-genre pairings of the late 2010s, bringing together a producer at the peak of his commercial and critical standing with one of the most commercially successful pop artists of the preceding decade. Anton Zaslavski, known professionally as Zedd, was born on September 2, 1989, in Saratov, Russia, and raised in Kaiserslautern, Germany. A classically trained musician who studied piano and drums before turning to electronic music production in his teenage years, Zedd signed with Interscope Records and rose to global prominence with "Clarity," his collaboration with Foxes, which won the Grammy Award for Best Dance Recording in 2014.

Katheryn Elizabeth Hudson, who performs as Katy Perry, was born on October 25, 1984, in Santa Barbara, California. By the time "365" was recorded, Perry had established one of the most remarkable commercial records in pop music history, with a run of five consecutive number-one singles from her 2010 album Teenage Dream matching a record previously held only by Michael Jackson's Bad. Her 2017 album Witness had underperformed commercially relative to those expectations, and her subsequent work was focused on maintaining her relevance in a rapidly shifting pop landscape.

"365" was released on February 14, 2019, Valentine's Day, a release date chosen deliberately to maximize thematic alignment between the song's content and the cultural moment of its launch. The song was produced by Zedd, who crafted a production that positioned itself between his signature electronic dance sound and the mainstream pop conventions more familiar to Perry's core audience. The arrangement features the synthesizer textures and rhythmic propulsion characteristic of Zedd's production style, layered with a vocal melody and hook construction oriented toward Perry's strengths as a mainstream pop performer.

The recording was made in Los Angeles, where both artists were based during the period of the collaboration. Zedd has described his production process as beginning from a melodic concept, building outward from a central musical idea into the full track, and his work on "365" followed that pattern. Perry's contribution to the writing is credited alongside Zedd and several co-writers, reflecting the collaborative, team-based approach that characterizes much contemporary mainstream pop production.

The song entered the Billboard Hot 100 on March 2, 2019, debuting and peaking at number 86 and remaining on the chart for one week. This was a modest performance relative to the profiles of both artists involved. The chart trajectory reflected a challenge that several major pop artists faced during this period: the fragmentation of the mainstream pop audience across multiple streaming platforms and format preferences made it increasingly difficult to engineer the kind of concentrated radio and streaming activity that had previously produced automatic Top 40 entries for major-label releases by established names.

In Europe, particularly in Germany and Switzerland, the song performed considerably better, benefiting from Zedd's strong following in those markets and the infrastructure of his existing fanbase in electronic and dance music communities. The song received substantial rotation on radio stations oriented toward dance-pop and electronic music formats, which were more prevalent in European markets than in the United States during this period.

The music video was directed with a visual concept centered on romantic continuity, depicting scenes of a relationship sustained across everyday moments throughout a year. The video accumulated approximately 160 million views on YouTube, a figure that reflected strong digital consumption particularly in markets outside the United States where the song performed more robustly on radio and streaming charts. The gap between video view counts and US chart performance illustrated the increasingly global nature of both artists' fanbases and the degree to which streaming geography had become distinct from radio geography.

Reception and Place within Both Artists' Catalogs

Critics noted the track's competence and the natural fit between Zedd's production approach and Perry's vocal capabilities, while also observing that it did not quite reach the heights of either artist's most celebrated work. Zedd's production credits on tracks like "The Middle" (a top-five US hit in 2018) demonstrated his continued commercial effectiveness, while "365" occupied a slightly different position in his discography, aimed more directly at mainstream pop radio in a way that may have sat between genre audiences without fully satisfying either. Perry's return to the charts with multiple collaborations during this period reflected a strategy of incremental re-engagement with the pop market following Witness, and "365" contributed to that gradual rebuilding of chart presence.
