So I heard this song in Attack on Titan towards the end of season 2 episode 12 and when I compared it to the soundtrack, I found out it was called "Attack on D".
However, the song in the actual episode (episode 12) has a piano part in it and the 'la la la' part only comes in towards the end of the song.
Is it a different song? If so, is it available in the OST?
