As a way to keep fans eager for her upcoming album, Prism, Katy Perry released a new song, Dark Horse, on iTunes. It features Juicy J and is far more urban than everything she's done so far (in my opinion at least). She stated on Twitter that this is just a taste of what fans can expect from Prism, out on October 22nd!

Katy Perry lançou hoje Dark Horse no iTunes como um single promocional do álbum Prism que sai a 22 de outubro. Este tema conta com a participação de Juicy J e é bem urban!
