The competition of digital chart is so strong, that even IU has never ranked 1st in the yearly music chart. Doesn't mean that IU has no other amazing records or anything like that.
Out of all these #1s, Big Bang is the only boy group and the rest are girl groups.
In the middle of that, three of the groups in this list are from JYP.
-iKON would be the perfect fit in this list..
-JYP is amazing.. And I'm not talking about Park Jinyoung..
-Out of all these 6 groups, 3 of them are from JYP..
-SNSD was the icon of that whole generation..
-Even the amazing Nobody lost to So Hot..ㅋㅋㅋㅋ Wow..
-Roly Poly was the bop of the year..ㅜㅜ
-Back then, Bigbang and Wonder Girls were my life.. They still are now..
-Bad Girl Good Girl was Miss A's song.. That's so amazing..ㄷㄷ
-Not to mention that Bad Girl Good Girl was a debut song..
-That's because IU mostly does her comeback by the end of the year..ㅠㅠ
-What song ranked #1 in 2013..? I remember Bounce, Bar Bar Bar, and Growl were the biggest hits back then..
-I believe that Twice has the possibility to rank #1 again someday..
-T-Ara was the miracle of small companies..
-Whoa.. Miss A's debut song ranked #1 in yearly music chart..
