Run Devil Run was released as the lead single to Girls' Generation's repackage album of
the same name. The single peaked at #1 on the Gaon chart and #2 on the Oricon chart.
I've heard both versions and obviously I like Ke$ha's more because I can understand it and I'm a Ke$ha stan, but Girls' Generation did a great job. It's a killer track! They did a good job of Chain Reaction, too.
when it's not 2NE1 leaving, they kick out Ke$ha rejects.
