KATE WALSH

Where You've Heard Her No, she's not the actress formerly of Grey's Anatomy. But the Englishwoman's yearning ballad ''Your Song,'' off her second album, Tim's House, was featured on Grey's. The disc, now available, even beat out offerings from Arcade Fire and Amy Winehouse to top the U.K. iTunes album chart last year.

For Fans of Dido and Joni Mitchell. The songstress, 25, marries whispery vocals with sweet musings on love and loss — all over acoustic guitar and violin. House teems with clean, no-frills cuts thanks to producer Tim Bidwell's homespun recording studio: his bedroom (hence the album's title).
