no1=CODENAMEZ (called in the JASRAC database, and called CODENAMEZ on the Xenoblade Chronicles X Soundtrack Selection) is Disc 1, Track 1 on the XenobladeX Original Soundtrack (making it the first track in 0rCH-SUITE "X") and Track 1 on the Xenoblade Chronicles X Soundtrack Selection.

 * The Zu Pharg appears over Sylvalum in.

Etymology
The no1= at the start of the track indicates that this is the 1st track on 0rCH-SUITE "X". 'CODENAMEZ' may be a reference to how the composer Hiroyuki Sawano gives codenames to tracks before he properly titles them: a letter/abbreviation followed by a number, where the letter/abbreviation corresponds to the soundtrack in question. In the case of Xenoblade Chronicles X, this letter was 'z' (Xenoblade X's Japanese name, ゼノブレイドクロス, can be romanised as Zenobureido Kurosu). As no1=CODENAMEZ was the first track composed for Xenoblade X, this title may be an indication of this early codenaming scheme.

The codename ('z' with a number) made its way into the final titles of some tracks, such as z5m20i12r04a28 and z29ba2t0t1l301e17.
