'Gangnam Style' remixes add giddyup to Psy's dance hit

Will Gangnam Style ever go out of style? Not this week.

The viral dance phenomenon by Korean sensation Psy, who became a global superstar after the kooky Gangnam Style video became the first clip to reach 1 billion views on YouTube, is getting a remix expansion Tuesday.

The Gangnam Style Remix Style EP, available digitally Tuesday on School Boy/Republic Records, holds four tracks, including a Diplo remix featuring 2 Chainz and Tyga, an Afrojack remix and two instrumentals.

The original Gangnam video, still racking up between 7 million and 10 million views a day, unseated Justin Bieber's 2010 Baby video as YouTube's most-viewed clip. It's also the most popular, with more than 5.8 million "likes" so far.
