I think she decided to put that sentence because the song is called 'memorial address', so it's like a speech you make during somebody's funeral. If you attend a funeral, you won't have the speech printed out for you, instead you have to listen carefully to what the speaker is saying

similarly here, ayu is making a funeral speech, and she wants us to listen to her carefully instead of just reading hte lyrics, sometimes it feels different and much more powerful when u close ur eyes and listen to the lyrics than to read the lyrics from the booklet

p.s. there are rumours that MA is about ayu's father's death...but we would never know unless ayu told us
