The dataset is 22 minutes long. It's made of songs from a couple different composers, as to not make it sound like a specific composer's tuning style or a specific Vocaloid version. It also includes some clips of Saki Fujita's voice taken from Project Diva X (ripped by Aloh).
Composers: kikuo, ryo, otomania, DECO*27, 40mP, toa, LamazeP, Omoi, VocaCircus
