Some say OST for this movie sucked, but I don't agree it has, like other Bleach movie OST, awesome tunes like this.
Aizen being sealed soundtrack comes from this movie
It also has nice lyrics
Spoiler for lyrics:
Cometh the Hour of our Reckoning, we will be ready
Cometh the Man who will Fight beside me and be steady
Cometh the Angel, the messenger from Hell we dreaded
Cometh the Devil's disciples, so we must be ready
My heart is strong, my faith goes on, but if my world is threatened,
I'll fight the fight, they'll pay the price, their blood will flow with vengeance!
The dogs of war will rip apart hostility unbounded,
And to the end our guns will roar until the enemy is CRUSHED
To the point of no return
Beg for mercy, scum of Satan
LUCIFER'S A CORPSE IN WAITING!
