Where does Roon get it's composer info from?

Hi, I am afraid I’m posing a stupid question again: I have two albums of the same album artist playing pieces of different composers. Both albums are set up the exactly same way in iTunes. In Roon, however, the composer for each piece is only shown for the older album, not the more recent. Does Roon get it’s composer information from somewhere on the web and not from the iTunes database, where the newer album may not yet be listed? Why is there not meta-data editing option for composers in Roon?

Search this forum there are many, many threads on this topic.

There is (see the section on “Link” edits).
