Those Jigsaw puzzle icons indicate the song infobox and the lyrics which are formatted in "poem" form. If you click on source while editing an article, you can see the lyrics and song infobox more clearly, though you will also see a lot of symbols which compose any kind of infobox while in source mode and <> symbols which compose formatting and "gallery" forms.
