Many Chinese pop singers are polishing their English-language skills to speak - and sing - to a global audience.

Zhang Liangying, aka Jane Zhang, is one of those ambitious - and capable - enough to release albums with English lyrics.

Her latest single, Dust My Shoulders Off, produced by US singer-songwriter Timbaland, reached the top five on the iTunes chart - a first for a Chinese artist.
