When we upload your music on Spotify, Spotify makes the artist connection and connects the release to an artist profile. This means that they will create a new profile or add the new release to an existing profile (hopefully the correct one!).
On some of the artist profiles, you see a blue checkmark which means that your profile on Spotify, is verified. The verification is available for all artists and there is no requirement of minimum number of followers any longer. You get access to Spotify for artists here: Spotify for Artists.
