I've found a clip of Ella's new song (坏女孩) released on SoundCloud by her record label , HIM music. Hope you guys like the song!

**P.S Soundcloud is a pretty good site on which some singers such as Yoga Lin and Evan yo as well as some producers share their never-heard-before music! For iPhone lovers , they have an app as well.
