2Volt

2Volt debuts as the third cut on the album accompanying the franchise's second compilation movie, subtitled Jiyuu no Tsubasa, which reached stores on December 16, 2015. A year and a half later the piece resurfaced on the Season 2 Original Soundtrack, holding the ninth slot on disc one of that June 7, 2017 release. Hiroyuki Sawano, who scored every entry in the franchise before The Final Season, wrote and arranged it; the full track runs 6 minutes 41 seconds.

Within its home film, the music underscores the opening recap, the Female Titan's destruction of Levi's squad, and the moment Eren shifts into his Titan form. The third recap movie, Roar of Awakening, reuses it twice, backing the Colossal Titan's ambush of the Scouts and the death of Hannes.

Television placements pile up across the series: episode 32 for that same Colossal Titan ambush, episode 37 for Hannes's final stand, episode 40 under Historia's account of her past, episode 43 as Grisha's memories cascade through Eren, and episode 54 for the duel between Levi and the Beast Titan.

The name is a riddle built on TheWeightOfLives: two volts equal one watt, so "2V" collapses into "W," giving "Wolt," an anagram of that title's capital letters, TWOL. The digit carries a second meaning, marking the piece as music for recap film number two.

One official remix exists, TWO-lives, distinguished by dropping the descending piano line heard between 1:19 and 1:45 of the original. The composition also borrows two ideas from theDOGS: its ostinato, surfacing near 0:26 and again across 3:07 to 3:21 and 3:59 to 4:12, and its chorus, which takes over from 4:36 to 5:25.
