It has been reported that there is as of the moment one K-pop video that already surpassed the 20 million mark in number of views as Girls' Generation's video for "Mr. Mr." exceeds 20 million views!
"Mr.Mr.", is an electropop dance song with a R&B sound, produced by The Underdogs, who has already worked with the popular international artists such as Beyonce, Justin Timberlake and Chris Brown.
The secret of the number of views maybe due to the concept of "Mr.Mr." is which as SM Entertainment described it, "classy, mystery girl" rather than "sexy" and stated, "We’re going to show a transformation that only Girls' Generation can show." The dance for the title song "Mr.Mr." is choreographed by choreographer Jillian Meyer, who has worked with Janet Jackson, Celine Dion, and Kylie Minogue.
The track, which is included in the album of the same title, has been digitally released on February 24, 2014 at 17:00 (KST). The album, consisting of six songs, was released worldwide through iTunes, Melon, Genie, and other online music portals. The physical album will hit stores on February 27, 2014. In addition, the group's first comeback performance has been scheduled for March 6, 2014 on M! Countdown.
A Japanese version of Mr.Mr. was released on March 21, 2014. However, there is no Japanese music video or physical single release for Mr.Mr. has been announced.
