When is the track "No differences" played? Track 01 on the Aldnoah.Zero Original Soundtrack is a vocal piece titled "No differences" (lyrics). It's positively eargasmic. Thing is, I don't remember it being played at any point during the show (and, given that the lyrics are English, I feel like I would have remembered it if I had heard it). Was it used? If so, when?

(Yeah, I could just rewatch it and listen for the track, but that would take a few hours I don't want to spend right now.)
It looks like "No differences" shows up for the first time in episode 2 of the second cour (episode 14 overall) at around 19 minutes in. My ears explode with delight.
