Last.fm scrobbling API中不返回更正

Last.fm scrobbling API的文档描述了元数据更正的功能。无论我发送什么请求，响应中的 corrected 字段始终设置为 0。

文档展示了当艺术家Bjork更正为Björk的示例。以下是我对艺术家Bjork的示例请求：

POST http://ws.audioscrobbler.com/2.0/ HTTP/1.1
Host: ws.audioscrobbler.com
Accept: application/json
Accept-Encoding: gzip, deflate

method=track.updateNowPlaying&artist=Bjork&track=Wanderlust&duration=351&album=Volta&api_key=*****&api_sig=*****&format=json

响应：

{"nowplaying":{"artist":{"corrected":"0","#text":"Bjork"},"ignoredMessage":{"code":"0","#text":""},"album":{"corrected":"0","#text":"Volta"},"albumArtist":{"corrected":"0","#text":""},"track":{"corrected":"0","#text":"Wanderlust"}}}

艺术家的 corrected 字段设置为 0。我从未见过任何情况下触发更正的情况，无论是艺术家、专辑还是曲目。

有人能为从Last.fm API获取更正提供建议吗？

我也尝试在Last.fm支持论坛上提出了这个问题，但没有得到答案。
