@Aderianu You can sing the entire song or the part you like the most. If many people join it I don't think some parts of the song are lost
@AyuWorld Yep!
@Linza-mo if you are too shy to sing you could do what @~angel*ayumi~ said. Just record yourself showing a message from Ayu or show the sky. Whatever you want. I didn't remember the parts in the middle of the song where nobody sings so I like the idea of fill it with people that doesn't want to sing

i'm gonna edit the first post.
