What is the song when Usopp is defeating Sugar by using his Haki? In One Piece episode 697, there's a song when Ussop is defeating Sugar using his Haki. It starts at 0:53 in this YouTube video.

What is this song? Is it already released as a soundtrack?
It is "The Straw Hats Gather and Head to Battle!" from the album "New World", track #44.
