"Junai no Crescendo" - AKB48

I'm currently going through an AKB48 phase. Their new album comes out next month, but on the same day as when the in-laws fly out :(

I discovered this song while watching their JCB Shuffle Concert, and I love it. Can't find a proper version without the crowd singing along though.

UPDATE: Fixed video link - it's the SKE48 version, but just as good.
