DJ­51 is a free app that analyzes the individual tastes of people in a room using their Spotify libraries and creates a playlist of music that reflects the collective musical taste of the participants.

DJ­51 was created by Cachaça 51, a Brazilian distilled spirit, as a brand experience that engages new and existing consumers, organically leveraging Cachaça 51 as a “cool and contemporary brand” in the US, according to a press release.
