"Counter Attack Mankind"* Tracklisted as "cóunter・attàck-m'ænkάɪnd", often played in the thick of a battle, especially those that have a heavy emotional weight, like Mikasa's epic struggle at the end of Episode 7 while embracing life despite the pain from Eren's apparent death. The later half's brass bombardment is sometimes omitted to emphasize the chorus, as shown during the first episode's sneak peek at the Colossal Titan's Signature Scene.
"Vogel im Käfig", the insert song sung by Cyua, is German for "caged bird". The first half of the song is used in a heroic instance, as a transformed Eren displays what Mikasa describes as humanity's wrath. The second, more recognizable part is played during Carla's death, Eren's first transformation into the Rogue Titan, and the Female Titan's brutal beatdown of the Special Operations Squad.
Eren: We're born free. All of us. Free. Some don't believe it, some try to take it away. To hell with them! Water like fire, mountains of ice, the whole bit. Lay your eyes on that, and you'll know what freedom is, that it's worth fighting for! Fight to live, risk it all for even a glimmer of real freedom! It doesn't matter what's waiting outside the gate, or what comes in! It doesn't matter how cruel the world can be, or how unjust! Fight. Fight. Fight. FIGHT! FIGHT!!!

Track 6* Tracklisted as "進撃 vn-pf20130524 巨人", which plays when the 104th's trainees don the Survey Corps' trademark cape for the first time, and when Mikasa desperately attempts to save Eren from the fleeing Female Titan's clutches.
