Hi, okay I have checked and in this case the song was not identified by SongKong and no match could be found. But it did copy the existing Artist field to Artists and Album Artists for consistency, but as the existing value in the Artist field is incorrect that hasn’t improved things
But it is added as Unicode, if your musicplayer does not show the value as added that implies your music player does not support unicode, if you don’t think SongKong is adding the information as unicode please send the mp3 file to email@example.com so i can check it.
Note if a song has a SongKong Id field it just means the file has been processed by SongKong, it does not mean is has been identified, if it has been identified it would have a MusicBrainz Track Id or a Discogs Release Url Id.
The summary shows how many songs have been identified, in your case it stands at about 50%, as Im sure you appreciate Chinese music is not as well represented as Western music in database. It wiould be worth rerunning as sometimes you can get a few more matches based on the partial information added in first run.
