I'm also happy count down is a full song, to me it was kinda expected as i thought it would be weird with an interlude after only one song (assuming that THE introduction wont be a full song).
Lol, Right now i think that Jump! will be one of the interlude^^ ( mostly because of the bunnyear-pictures ayu posted
)
But, still, I have no way of knowing anything about RnRC's music(and because of that, the antisipation for the album is killing me xD).
