A happy-go-lucky ska beat accompanies Brit singer/songwriter Lily Allen's second single, as she frolics on a bicycle across London—or "LDN"—observing things are not always as they seem: "A fella looking dapper, then I see it's a pimp and his crack whore." Despite the message that "everything seems nice, but if you look twice you see it's all lies," cynicism is on the down-low, as she further surmises, "Sun is in the sky, why would I wanna be anywhere else?" She's got a point: Considering stateside programmers' refusal to indulge the greatest U.K. invasion in a decade—leading listeners online to discover should-be hits from Allen, Mika, James Morrison, Joss Stone, Keane and Amy Winehouse (albeit "Rehab" is getting props)—"LDN" is beating stateside tastemaking to a pulp. —Chuck Taylor
