The girl group is getting ready to release their first all-Japanese single titled "One More Time". So far, several teaser images and two MV teasers have been released. The full version is coming out on October 18 but it seems some people are listening to it a few weeks earlier than they're supposed to.

Recently, a link to a music streaming site giving access to the full version of "One More Time" roamed the web, and the new song was also shared on YouTube. The leaked content has been blocked in many countries with YouTube's copyright detection blocking the song on behalf of WMG (Warner Music Group), however, many people claim that they've already heard the full song. 

Fans hope the official release date will be respected and no further complications will occur regarding TWICE's first Japanese single.
