The album, which contains TWICE’s past hit songs both in Japanese and Korean, topped nine Apple iTunes charts, including those in Japan, Indonesia, Macau and Malaysia, upon release.

The nine-member group, which has two Japanese members, has sormed the K-pop scene since its debut about 1 1/2 years ago. Starting with its debut song “Ooh-Ahh,” TWICE has had five consecutive No. 1 tracks in Korea. The others are “Cheer Up,” “TT,” “Knock Knock” and its most recent hit track “Signal.” (Yonhap)
