Their popular song "FIRE" is their fourth MV to reach such a feat. This is especially significant because they are the first and only K-pop group to have four music videos receive so many likes. It has only been a week since "Not Today" received 2 million likes as well and for them to reach this goal once again in such a short span of time is certainly amazing. If you'd like to see the video again or haven't yet, check out the clip above! 

Congratulations BTS!
