Before today, 2NE1 held the record of the most viewed debut MV on YouTube for a K-Pop girl group with the space version of their track "Fire," which accumulated about 41.4 million views. However, this has been broken now by TWICE whose debut MV for "Like OOH AHH" has just hit 41.5 million views!
On top of that, the girls may continue to move on to becoming the most viewed debut MV ever if they surpass NU'EST's record of 46 million views for "Face." Considering how quickly their view count is going up everyday, this may indeed be possible. This is definitely an impressive feat, even more so considering that "Fire (Space Version)" has been out since 2009, but "Like OOH AHH" has beaten that in a span of months.
Both MVs are a must-watch either way so revisit them when you can!
