K-Pop star Psy's new single, "Gentleman," ranked 12th in the Billboard Hot 100 chart updated Wednesday, according to its official magazine.

It is the second time that Psy has entered the main chart of Billboard, following "Gangnam Style," which swept the global pop music industry last year.

The new song "launches at No. 1 on Streaming Songs with 8.6 million streams registered in the U.S. in just shy of two days since its posting on Saturday," the Billboard Biz said.

The rise of both songs was apparently driven by huge popularity on YouTube.

The new one, released just five days ago, has already recorded more than 125 million hits.

Psy plans to arrive in the U.S. this weekend to promote "Gentleman," a visit that is expected to help spur its popularity.

"Gangnam Style" entered the Billboard ranking at 64th and galloped to second. But it failed to reach the top.

It became the first video ever to reach 1 billion views. It now stands at 1.5 billion. (Yonhap News)
