Spotify has created an interactive data visualization called Musical Cities, which uses distinctive playlists to represent music preferences in over 1,000 cities across 59 countries. The playlist is based on 23 billion listener/track relationships and features unique songs that are popular in each city but not elsewhere. This map provides insights into international music tastes and can be used for travel planning, business purposes, or personal exploration of local sounds. Spotify's collaboration with CARTO has expanded the meaning of location intelligence by transforming data on aural behaviors into visual information, redefining what it means to understand "where" through music. The Musical Cities map also features a playlist called CARTO Tunes, which showcases songs with lyrics related to maps and geography.
