Today, SM Entertainment officially revealed SNSD's jacket photo of their second repackage album, Run Devil Run. As seen below, the jacket photo reveals a female wearing tight black clothes expressing a charismatic pose. Many of you have probably been wondering who this mysterious figure is. According to a representative of SME, the female in the jacket photo is, as some of you might have guessed, YoonA! Rather than exhibiting her usual cute and fresh image, she is seen with a completely different concept. Along with Run Devil Run, it's been announced that two news songs will be added into their repackage album. The first one is titled Echo, and it will have fresh melodies and rhymes. The second track really isn't new because it is an acoustic R&B version of their track Star Star Star. Fans who purchase their repackage album will receive special gifts as the album will include each of the members' posters. Stay tuned to their repackage album which is scheduled to be released on the 22nd, and also SNSD's story version MV of Run Devil Run. And don't forget to catch their live performance on this week's music programs, starting with KBS Music Bank!
