See also the Lists - Artists section.
The artist name and biography may be entered.
If the artist is changed, you will be prompted as to whether or not you want all of the Albums and Songs that used the original artist name to use the new value.
If the new artist value duplicates another on file, this will be noted and the change not saved, but you can still have all of the Albums and Songs that used the original artist name changed to the new value.
You may then wish to delete the old value from the Artists list.
This feature is primarily intended to allow you to keep a standardized list of artists, and make it easier to find all of the songs for a particular artist under one name.
