My Universe

My Universe relies on one of modern pop's most durable harmonic blueprints — the I–V–vi–IV cycle in A major — which is both its commercial strength and its intentional design. Co-writers Max Martin and Oscar Holter, veteran architects of stadium pop, made a deliberate choice: keep the harmonic canvas simple so the bicultural novelty (English and Korean vocals, two globally distinct fan bases) and the synth-pop production do the expressive heavy lifting. The verse's vi-entry softens the tonic into a minor-tinged longing, while the chorus's triumphant reset on I converts that longing into resolution. There is no modulation, no borrowed chord, and no chromatic movement — the song's distinctiveness comes from timbre, bilingual lyric, and the sheer cultural event of the collaboration rather than harmonic innovation.

Chris Martin received a message about 18 months before the song's release saying BTS wanted to collaborate. Initially unsure how it would work, Martin was inspired when a friend casually used the phrase 'my universe,' which he noted down as a potential title. He then developed a demo specifically for the collaboration with BTS. Coldplay originally wrote the song for BTS, but the creative process was revised so the Korean septet could contribute directly to the songwriting.

"My Universe" is a landmark collaboration between British rock icons Coldplay and South Korean pop phenomenon BTS, blending synth-pop euphoria with bilingual lyrics in English and Korean. Released as the second single from Coldplay's Music of the Spheres, it debuted at number one on the Billboard Hot 100, making history as the first song by two co-billed lead groups to top the chart.
