It hasn’t even released a single note of music, but newly formed K-pop group X1 is already making waves on the Billboard charts, debuting at No. 6 on the Social 50 tally dated Aug. 17.

The Social 50 is powered by data tracked by music analytics company Next Big Sound and ranks the most popular artists on Facebook, Twitter, Instagram, YouTube and Wikipedia. The chart's methodology blends weekly additions of friends/fans/followers with artist page views and engagement. The chart's latest tracking week ended Aug. 8.

Some backstory: X1 formed via Produce X 101, a K-pop survival reality show that aired from May to July in South Korea. At the close of the series, the 11 remaining members (from an initial 101) became part of X1.
