MIDI transcriptions from YouTube channel EpreTroll

MIDI covers by CaraPrincess (CP104).

Fanarts of Mettaton found on the site Safebooru.

Tracks:

Idol Pandemonic (アイドル・パンデモニック)

Original: Pandemonic Planet (Hecatia's theme from Touhou 15 Legacy of Lunatic Kingdom)

Comment: I'm currently experimenting with the electro-rock genre, and this track is given a harsh and aggressive atmosphere, true to the track's title, Pandemonic. The guitar overdrive in this track also somewhat resembles the guitar overdrive used in most MEGALOVANIA-styled Touhou remixes.

Ahh... Mettaton, the yang as opposed to the yin of Jane's personality: Prideful, but still as charismatic as an angel. As ZUN describes the original track as a bit demonic, this track suits best an idol robot who came from the Underground, albeit the Underground of Undertale is not as scary as other underground realms, but one thing that makes venturing the Underground dangerous, as in the story of UT, is Asgore and his colleagues.

Mechanical Angel Girl ~ Robotic ☆ Angel (機械的天使の少女〜Robotic☆Angel)

Original: The Wheel of Fortune Turning Over (Sagume's theme from Touhou 15 Legacy of Lunatic Kingdom)

Comment: Compared to Idol Pandemonic, this track is given a more light-hearted atmosphere due to the usage of the synth celesta and trumpet instruments, but still keep the electric guitars of modern pop and rock music and the saw lead of electronic music.

Ahh.. Jane, the Angel of All Idols (even though she is not actually an angel; she is a robot with a soul), and the yin as opposed to Mettaton's yang: Humble, while still being a cute and charismatic girl with amazing singing abilities. But her singing abilities also comes with a cost: She has the ability to mainpulate others' thoughts and motives through singing, so she might cause serious consequences if she use this ability in an improper way, such as causing a mass suicide upon singing a song related to death in front of a large amount of audiences. So as a result, she become wary of her singing ability, and she only sing for the local church choir or singing Christian pop songs that have lyrics that refers to giving praises to God in her concerts. Nevertheless, despite being not the type of idol that everybody knows, but being a type of Christian music idol who spend time singing praises to God, so many people considers her to be an angel incarnated in human form, and loves her as if they are loving their loved ones.

Hope you enjoy this cover compilation!
