And another - IQ: https://open.spotify.com/artist/0DQ9JcIWMGVzlQSfCVK4oN. Both the British prog band I was looking for, a rapper, and some world music artists. I have very wide tastes in music, which is part of why I like streaming services, but it would be nice for Spotify to put a little effort into fixing the database.
Others have suggested simple solutions - a tabbed interface with a tab for each artist of the same name would be ideal. It just takes a unique database identifier for each artist of the same name, which the user doesn't need to see. This is a problem on other streaming services as well, but there should be an easy way for users to report, and a well-defined response from the provider. At the very least, there should be some indication that someone is paying attention.
I am an artist on Spotify with the name Eric Best, playing a reggae folk fusion thing and then there's a rapper with the same name dropping N bombs every other word. It's a conflict of interest really... Spotify needs to figure it out. It's streaming 101.
