SNSD (Girl's Generation)

This is a 9 member female group under SM Entertainment formed in 2007. Their most popular song was "Gee", but recently they released 2 tracks that have been receiving a lot of attention. The 1st song is titled "Oh!" and has a cutesy, girly concept. Soon after they released "Run Devil Run", which takes an opposite concept of dark and sexy.
See for yourself...
