I know I give Final Fantasy a hard time: the games, the endless remakes, the character designs in recent years, the fact that Square Enix are physically incapable of going more than 3 months without releasing or announcing a new game in the series, it's all fair game as far as I'm concerned. It used to be that a new Final Fantasy game was an Event, something to get excited over. Now, you'd be as well getting excited over it being Tuesday.
That said, the one department Square has never once dropped the ball in, is the music. Say what you will about the legions of androgynous girlymen, When it comes to the music, Square has never once lost its teeth. Crisis Core, while exemplifying many of the problems I have with current-day Square Enix, also had a solid OST, featuring a mix of redone themes from FFVII and Advent Children, as well as a variety of original work. This track, The Summoned, is a redux of the classic FFVII boss theme, arguably as it should always have been. If this doesn't get the blood fired up, nothing will.
