The product that failed to import the ratings from MusicMatch was Media Center 12.0.251 which I presume is the lastest and greatest.
Bummer. Yahoo has stopped supporting MusicMatch and is trying to force people to "upgrade" to Yahoo music which is very limited in features compared to MusicMatch. (For example, no expandable directory view of artists, genres, albums, ratings. No ability to sort in views as there are no views. No smart playlist feature.) There is a great opporutnity here for someone to pick up the ten million or so abandoned MusicMatch customers, but it doesn't look like it will be Media Center if it doesn't import MusicMatch tags (which are stored in the mp3 file, by the way, so it is not a hard technical problem).
By the way, KingSparta (or should I call you Leonidas?), I went to Thermopylae last month on my way back from Mycenae and Troy. Awesome experience.
Thanks for trying to help.
