Try putting the text in a 2-column table with the song title in the left column and the song text (lyrics) in the right column. Then 'Sort' the left column alphabetically and this should keep the right column text with the left column as it gets sorted. The table borders can be formatted as 'None' if you don't want them visible.

This means the title will be to the left of the lyrics but that is the only downside I can see.
