N市L街A

N市L街A (called on the JASRAC database) is Disc 3, Track 4 on the XenobladeX Original Soundtrack. It is split into two parts: the first plays from the start until 2:31, and the second plays from then until the end. Despite its name, it is unrelated to N周L辺A.

The first part plays in NLA during the day, and the second part plays at night.

Etymology
The kanji '市街' in the title mean 'city', so this track's title can be taken to mean 'the city of NLA'. The JASRAC version of the title can also translate to 'NLA City'.
