There is nothing I can comment on that has not been discussed much deeper than it has already been, so I'll just add my own small comets.
Aside from what everyone has said about this episode, it showcased Ono's heroism and selflessness. As Hadithi himself commented. Even with his wing trapped Ono's concern was for others.
I agree that there does not need to be a song in every episode. Unfortunately the shows creators think they need the songs to keep The Target Audiences' attention. That makes me doubt that they care if the songs are becoming similar, or if they are burning out their music crew.
