Learn English – Is a piece of electronic music a song or a track

The term cantabile is used (usually in classical music) to refer to pieces or passages which are "song-like":

Cantabile is a musical term meaning literally "singable" or "songlike" (Italian). It has several meanings in different contexts. In instrumental music, it indicates a particular style of playing designed to imitate the human voice. For 18th century composers, the term is often used synonymously with "cantando" (singing), and indicates a measured tempo and flexible, legato playing. For later composers, particularly in piano music, cantabile indicates the drawing out of one particular musical line against the accompaniment (compare counterpoint).

In classical music tradition such a dramatic break in the music (not so much a false ending) is called a grand pause, a caesura, or very informally, railroad tracks.

A grand pause is a more expansive break, often notated with a whole measure of rest, sometimes with the initials "G.P." over the bar.

A caesura is typically a shorter break that often happens abruptly. It's notated with two right-slanting parallel lines (looking like railroad tracks, whence the informal label) that can be placed at any point within the measure.

Your Yanni example is somewhere in the middle of the two, and could be appropriately called either one - either a shorter grand pause or a caesura.
