London-bred singer Estelle's stateside debut, "Shine," is heaving with catchy, instantly likable hip-hop/R&B/ pop songs produced by the likes of Will.i.am, Wyclef Jean and Mark Ronson, to list a few, and featuring Kanye West and Cee-Lo, among others. "No Substitute Love" samples George Michael's "Faith" and features the 28-year-old songstress belting out about dumping a mischievous boyfriend; she croons about wanting to formalize a relationship with a part-time lover on the piano-laden "More Than Friends." "So many search to find love that's as good as mine," a confident Estelle sings on the reggae-tinged "Come Over." And then there's "American Boy," the best-known track at this point, a charming duet with West in which she pays tribute to the North American XY chromosome.—Mariel Concepcion
