[Feature] Add song metadata to .lrc file.

[Dr-Blank]

Could the .lrc files contain the song metadata along with the lyrics.

The ID Tags would be inserted above lyrics as below:

[ar:artist]

[al:Album where the song is from]

[ti:Lyrics (song) title]

[au:Creator of the Songtext]
[length:How long the song is]
[by:Creator of the LRC file]

[offset:+/- Overall timestamp adjustment in milliseconds, + shifts time up, - shifts down]
 
[re:The player or editor that created the LRC file]

[ve:version of program]

[la:EN]

The song title, artist and album information are already available.

This should be overall fairly easy to implement, but I don't think Spotify provides lyrics metadata such as author/player through their API.
