Both of BIGBANG’s songs from the ‘E’ part of their series continue to crush the music charts.  
The two songs have been battling each other for supremacy on the music charts, but it should come as no surprise that it’s the more heartfelt “Let’s Not Fall In Love” that seems to really be hitting a chord. After achieving an all-kill upon release, the song has gone on to obtain not one, but two perfect all-kills, taking the top spots on all of the real-time, daily, and weekly music charts at the same time! 
Of the four songs that have earned perfect all-kills in 2015, two of those songs belong to BIGBANG. “Loser” also earned a perfect all-kill (3 actually) as did Miss A’s “Only You” and SISTAR’s “Shake It”.

Congratulations to BIGBANG!!!
