ITunes album cover is not the correct cover for that album

you can always use Apple Feedback page to submit any kind of request.

if you have this problem in our own iTunes Library, it is easy to assign a new cover to the song or album by just dragging the cover to it or using the GetInfo option, you know how to do this right?

if you install Last.fm app you can simple play a song and then drag the last.fm cover into the artwork of the iTunes song.

I've only ever seen this happen when the metadata absolutely differs in some way between tracks. There are two ideas that come to mind:

1. Highlight each individual character and make sure 3 dots ( ... ) haven't been transformed into a single character elipses ( … ). Highlight each of the dots above and you should understand the difference.

2. Check the 'Sorting' section too and make sure all of that data is identical, notably in the 'Grouping' fields.
