No11=RE:ARR.X

no11=RE:ARR.X (called on the JASRAC database) is Disc 1, Track 11 on the XenobladeX Original Soundtrack (making it the eleventh and final track in 0rCH-SUITE "X"). It is split into two parts. The first plays from the start until 3:03 and is a remix of So nah, so fern (and, by extension, of X-BT3). The second plays from 3:03 and is a remix of no2=THEMEX.

The first part of the track plays immediately after the fight against the Prog Ares in. The second plays when Elma activates the backup power to the Lifehold Core in.

Etymology
The no11= at the start of the track indicates that this is the 11th track on 0rCH-SUITE "X". 'RE:ARR.X', i.e. 'Rearrangement X', likely indicates that this track consists of remixes of other XCX tracks.
