Halloween // The lyrics to nightmare on my street changed and I don’t know why

So as any normal would do I was listening to my Halloween playlist in February and it got to the song “nightmare on my street” by Will Smith (for context I know all the words and was singing along) and I noticed that some new lyrics were added, nothing taken out but new lines in between lyrics. I added that song on the playlist last year and haven’t re-added it or anything like that and google won’t give me answers. So I am asking, dear Redditers, why might this be?
