Leona Lewis allowed fans to get a sample of what to expect on her upcoming album, 'Glassheart' slated for an October 15th release. On a recent visit to a UK radio station Lewis debuted the album title track for listeners. The uptempo dance number is something very different for the singer to take on. It's certainly worth checking out. Glassheart is shaping up to have great range and this track is superbly done!
