Japanese Idol-Group Music Corpora

Five idol-group performers singing and dancing with microphones

We develop and document corpora for music in the style of Japanese idol groups. FruitsMusic collects real-world Japanese idol-group songs, while IdolSongsJp provides a multi-singer song corpus in the style of Japanese idol groups. The two datasets support music information processing and multi-singer music research.
