The joy in Lily Allen's music comes from the thrilling contrast between her whisper-soft, welcoming voice, sweet pop melodies and vicious lyrical barbs. Her most caustic songs—from the country twang of "Not Fair" to the ska-infused "Ldn"—dissect modern society with a childlike glee. But it's not all finger-pointing and snark; the bassquake of "Hard Out Here" reflects ruefully on her own place in the celebrity-obsessed culture of the '10s, while twinkly pop confections like "Littlest Things" are honest depictions of a young woman knocked sideways by the roller-coaster of love.
