I'd like to move a part of my music library from JRiver MC 22 to iTunes, to make use of my library on Apple TV. The artist, album, title (and a few other) tags are OK, but there is still quite a lot of info I'd like to take with me to the iTunes library. (Playlists are rather easy to handle, but ratings seems impossible.)
Anyone who have gone through this process before and have some helpful hints?
