See the attached image:

I just added Diana Panton's "Red" to my library. Artist View is showing the correct songs under Diana Panton, but with Taylor Swift's "Red" as the album cover.
I know I've reported this issue before, with examples of albums called "Greatest Hits" all using the first located album art for an album called Greatest Hits for ALL albums with the same title.
EDIT: it gets better... see the attached image #2:

...clicking on the PLAY button in Artist View incorrectly enqueues Taylor Swift's version of Red, not Diana Panton's version.
