The Dayeinu can be sung or read and the importance of it is to share the story of the Jews being enslaved in Egypt and leaving. I think the Dayeinu is important in the sedar because it can share the story of Passover in a better way of understanding and remembering. In a form of a song, the Dayeinu also tells us that Hashem has performed miracles for us.
