Do you ever listen to a song you don't know all that well and you keep singing the same lyric over and over again because it's the only part you know?

That's what I'm doing with this one song on Arcaea, only because it's so random. "If I were a circle, I'd give you my circumference." I don't even know what that means even with the context of the song (which also makes no sense).

Either that, or it's a song in another language and you can only say the parts in English. That would be me with any song in Japanese. (BOYS BE AMBITIOUS, LIKE THIS OLD MAN)
