Winning songs

1st Song Contest

The first song contest was announced on April 21, 2022. Applications started on May 1, 2022 and ended on July 31, 2022.<ref name="1st held">

What's up? Pop!, the winner of the 1st song contest

The winning songs were What's up? Pop! by Capchii, Yaminabe!!!! by cosMo@BousouP and Jinsei by Ann-MeltsP.

What's up? Pop! was added on December 23, 2022.<ref name="1st winner"> The judging comments for What's up? Pop! were:

キラキラかわいいPOPでfutureコアな楽曲で、音数がかなり多く複雑なノーツ配置にできそうです。ミクの声もかわいい成分多めで楽曲に合わせて作られており、高速で複雑なだけではなくボカロ曲としても素敵な１曲です！全体がハイクオリティで超高難易度楽曲となりそうな楽曲なため採用とさせていただきました！

Yaminabe!!!!, the winner of the 1st song contest

Yaminabe!!!! was added on March 4, 2023.<ref name="1st winner"> The judging comments for Yaminabe!!!! were:

BPMの激しい変化に加え、最大BPM300という超高速。ただずっと高速なだけではなく、低速も混ぜ込まれた揺さぶりがプレイしている人を想定して作られたかのようないやらしさをしています。さらに歌詞にも「これが真のラスト一撃」などリズムゲームとしての遊びも随所に散りばめられていて、超高難易度としてふさわしく採用とさせていただきました！「覚悟を決めて召し上がれ」という歌詞がぴったりな譜面になりそうです。

Jinsei, the winner of the 1st song contest

Jinsei was added on June 2, 2023.<ref name="1st winner"> The judging comments for Jinsei were:

バーチャル・シンガーを6人使った複雑な曲にも関わらず、それぞれのパートでキャラらしさも出しながら曲調が大きく変えられておりリズムを取るのが難しそうです。曲終わりの高速パートもシンプルに難易度を上げる要因になっていて超高難易度となりそうなため採用とさせていただきました！

概要欄にある”音ゲーマー25年目、ボカロP15年目の全てがここに。”というコメントを存分に感じられるかと思います。

2nd Song Contest

The second song contest was announced on July 27, 2023. Applications will start on August 1, 2023 and end on October 31, 2023.<ref name="2nd held">

The winning songs will be announced in November 2023.
