I think Media Center is a great on-computer music player. I'm very happy with it in this regard (although it does seem to have trouble playing nicely with Sonarworks True-Fi; it seems I often need to fiddle with the playback options to get it to work correctly).
However, the main reason I initially purchased it was to manage my music library and sync it to my portable player. This has created some headaches for me, because Media Center has major problems handling special characters. It continually re-syncs all songs that contain special characters in its tags, creating an additional copy of each file every time it syncs. It seems the only way to prevent this is to eliminate all special characters from every tag which, in this day and age, seems extremely archaic.
Since this is quite and old problem that has yet to be resolved, should I just assume it will never be fixed?
