Talk:砂の惑星 (Suna no Wakusei)/@comment-68.99.178.46-20171004151935

Come to think of it, I was looking at the lyrics again and the line " Come to think of it, today is our happy birthday" reminded me of "Birthday Song for Miku" that Michie M made for her 5th birthday. Is this a reference or just a coincidence/non-intentional?
