Besides their catchy tunes and boyish good looks, BTS has got a strong Instagram presence with their concept photo sessions. But their Twitter game is even stronger, being named by Forbes as the most retweeted artist on the platform. And it doesn’t stop there! In November 2016, BTS made it to the top of the Billboard Social 50 list, a first for a KPOP band. Just like their debut album claimed, these boys are 2 Cool 4 Skool.
