Hey @MicahSherwood we want all the world’s music on Spotify. However, some artists and tracks are not currently available. Sometimes agreements can’t be reached with the artist or label or a change may happen in music ownership.
Thousands of albums and artists are added to Spotify every day. If you can’t find an artist you’re looking for, they may appear (or reappear) soon.
In the meantime, feel free to contact Chance the Rapper's label to ask when the tracks will be on Spotify.
