21. Lianne La Havas, 'Is Your Love Big Enough?'

The British folk and soul singer infused her debut album with influences like Nina Simone and Lauryn Hill. While some tracks chronicle La Havas' past relationships -- including a tell-off to an ex who wanted to leverage her success -- many celebrate the singer's happiness in feeling completely herself.  La Havas' voice is not one for power ballads, but listen carefully -- you'll want to hear what she has to say. -- Maggie Malach
