@AutumnBand listening C....de I am so proud of you!!! It's magic. Btw B.g S...der is such a big song!!!!!! Miss u
I think the 'C....de' is the title of the song with 4 letters missing, and earlier a blog who claims to have heard the song titled their article 'when we collide'. Therefore I think the name of the single is Collide
