You have to submit the metadata update to the spotify team to update the name, label, or needs of the distributor.
The team cannot make changes manually until the team gets the metadata. Once spotify receives updated info from the distributor or changes made by the user according to the delivery of the metadata.
In case if you deliver music through the recommended or preferred distributor then you can contact the team to fix the music. One can contact distrokid, record union, vydia, cd baby, and emubands.
The distributors use the best practices to reduce any problems related to metadata. They also let you deliver music with the particular id of the artist that helps in preventing the music mixing in the future.
