This is a strange issue (maybe more of a feature request)
I like to do all my editing with the keyboard to navigate around. I noticed that with the title field, I can hit enter and the cursor is active in the field for editing.
With the artist field however, when I hit enter, I have to then click in the field to edit it. It seems to be the only field with this issue that i have found.
Bug? Easy Fix? 
Thanks
