Description of the issue
Weird error: composer propagation via artist. Album and artist correctly identified, but in addition to actual composer, all composers of e.g. Emerson String Quartet albums in my library also show up as composer. I have multiple issues of this kind.
That album has a 3rd bonus cd with all those additional composers to Haydn on it. So the credits on your screen shot are what I would expect to see. Do you have a different example with unexpected composer credits?
