BBC: Four or five more songs like that from contributing writer Emeli Sandé, maybe a collaboration with Jessie Ware, and this would feel like a fresh start. As it is, it’s simply the next Leona Lewis album.

Digital Spy: Like many artists before her, Leona has channelled the darker side of love's grasp into her work - and the result is nothing short of spectacular.
Washington Times: Leona Lewis is a fantastic, savvy singer whose vocal chops always seem to outshine her songs. By focusing on hip, detailed dance music instead of gauzy ballads, though, “Glassheart” puts the two on equal ground.
