What is the problem you are facing?
When the same artist releases Albums under separate names, I would like to be able to merge the two artists.
e.g. Jimi Hendrix and The Jimi Hendrix Experience
Renaming The Jimi Hendrix Experience to Jimi Hendrix with the new edit tools leaves me with 2 Jimi Hendrix artist entries.
What are the possible drawbacks or issues with the requested changes?
None that I can think of, but the user should be able to choose what the final Artist name is post-merge.
