I wanted to highlight the songs with lyrics and songs that are only instrumental and songs that don't have it at all, so to insert.
As per image.
In practice, in the track list, the highlighted field changes color.
f the text is present it turns green, if the piece is only instrumental, I insert this manually, it turns yellow and if it is empty it remains red.
It always remains red even if the text is present.
If I insert the text in the file it turns green but it doesn't remain after it turns red again like there was no text but there is.
