If you found a particular lyric or lyrics on the site that has the wrong song credits please post the URL of the lyrics with the song credits corrections.
There is no real guideline for the wording and name convention but it is recommended that you credit at least the lyricist along with the singer. Without lyricists, there will be no lyrics.
You will not be credited with any song credits correction. Should you wish to post a correction of the lyrics together with the song credits, please do it in a separate thread/topic.
