Entropical

Entropical is a song performed by SashiMori.

Description
Entropical is a rock song. It features multiple voices singing in different manners, including a female voice and a deep male voice, implied to be sampled human voices. The song starts with the female voice singing mostly quietly, sometimes shouting, with the male voice rapping in between. During the chorus, the female voice gets slightly louder. After the chorus, the music tones down, reducing the volume and loops. Like all battle songs, it has a random chance of being played during online matches in Splatoon 2, and was added in Version along with the other SashiMori song, Chopscrewey. It was first heard in the Version 4.0.0 trailer, and later a snippet was released, revealing the name of the track. It can also be heard in Squid Beatz 2, with a maximum score of 194 and 311 in Normal and Hard modes, respectively.

Entropical (Splatoon 2 Ver. 4 trailer)
Entropical was first heard during the used for the trailer for Version, containing an extended section added after the intro and a proper outro to fit the anime style of the trailer.

Entropical [Live]
The live version retains most of what is heard in-game. After the intro and the chorus it transitions synthesizer solo followed by some guitar strings. This goes back to chorus for a second time. After that, ending with an outro similar to one used in the Version trailer.

Trivia

 * In the trailer for Version, a Splat Bomb is thrown at the same time as the chorus begins. This may or may not be related to the chorus sounding like the word "bomb" being sung.
 * In-game, this song is not fully looped to fit better within two minutes and leave sixty seconds for Now or Never! in Turf War. This is shared with Sucker Punch and Wave Prism. It is fully looped on the album version.

Etymology
'Entropical' is a portmanteau of 'entropy' and 'tropical'. This could refer to the degree of disorder or randomness caused by the sampled voice clips used to make the vocals of the track.
