[Machine Translation] Ms. OOJA Cover Album Vol. 4! This time, we have changed the theme of the album from the previous three albums, covering "only the hit songs that once reached No.1". The key points of this album are: (1) Songs that have reached No. 1 in the music ranking! (2) Theme songs, commercial songs, and other songs that have been played on TV many times! (3) Focusing on songs from the 1990s, when 30-somethings were in their youth!
