There is no single database containing information about an artist's country of origin, so we use multiple data points such as biographies on Spotify, Apple Music, Wikipedia and Facebook to automatically determine the most likely country of origin and aim for a 98% match rate.
Also, many management companies and agents will supply data to us for updating and to fill in blanks. Sometimes, manual updates can result in conflicting city and country data though!
To add or correct the city/hometown and country for an artist please send the following details via our online chat (icon in bottom right corner).
