Song: Halcyon Days
Artist: Siobhán Donaghy
In short: The first member to disband from the Sugagabes, Siobhán Donaghy, has released two solo albums since parting ways with the other members. Her sophomore album saw her working with producer James Sanger, whose production credits include U2, Keane, and Dido. The ethereal “Halcyon Days” is a moody number dotted with rays of hope; Donaghy sings so delicately, as if the melody could be broken by a puff of air. Sound-wise, “Halcyon Days” is the kind of song you’d imagine mermaids singing deep down in the ocean.
