Etymology
The track title can be split into 3 parts: the prefix 'z23', the digits '20120914', and the letters 'sama-ru'. The letters likely reference the Samaarians or the Samaar Federation (the hyphen may be a reference to how a horizontal line indicates a repeated vowel in Japanese). The digits can be interpreted as the date 2012/09/14, or the 14th of September 2012, possibly the date in which the track was composed or recorded. The track is one of several in the XenobladeX Original Soundtrack beginning with 'z' and a number (possibly followed by 'b'); the significance of this is unknown.
