I have several songs on more than one record - for example, on a record by "various artists" and on one of the band's own records. It would be nice if there was a button on the Credits and Musicians tabs that would copy the contents of these tabs to the clipboard (or some other volatile storage) and another that would paste the contents of such storage into a song's credits. If there's nothing in the bucket the button should be disabled. If there are already credits in the song, then the Paste button could either overwrite them, or better yet offer the user a choice to either overwrite them or append them.
