Sofi Tukker, a New York City house music and EDM duo, is comprised of Sophie Hawley-Weld and Tucker Halpern. This duo has been making music together since 2014, and has other notable songs such as "Drinkee," "Best Friend," and, of course, "Purple Hat." Because Sofi Tukker has found popularity thanks to their upbeat tunes, they have since lent their music to TV ads, such as a Michelob Ultra commercial in 2019 and the PrettyLittleThing clothing ad — produced in concert with ZHU — in 2020. While these songs weren't specifically made for the commercials, they do fit in quite nicely with the aesthetic and tone that the commercials aim to capture.
According to an interview with Entertainment Voice, Sofi Tukker's purpose on the song is to bring back a modernized theme of "Studio 54 New York, kind of like a weirdo, club kid kind of vibe" so that the current generation can experience that feeling too. Sofi Tukker often contributes music to the National Alliance on Mental Illness (NAMI), demonstrating that mental health is just as important as physical health, which makes their music a philosophical fit for Peloton as well as an aesthetic one.
