Delicate phrasing, with both voice and guitar, has always made Richard Thompson a musician worth hearing — and sometimes even liking on a personal level. For a man who can make such pretty music, it's to his credit that he prefers to show his thorny, stubborn, cranky, even mean side in many of the songs in his solo career.

"Telescope," the fictional hit single by the fictional country star Juliette Barnes on Nashville, is sung by the actress who plays Juliette, Hayden Panetierre. If it didn't become a real-life hit when the song was released a few months ago to country radio stations, it wasn't for lack of catchiness, courtesy of producers T-Bone Burnett and Buddy Miller.

Ke$ha uses a dollar-sign instead of an "s" in the middle of her stage name. It's one of those gestures that's meant to bait her detractors — suggesting before anyone else does that she's only in it for the money. It turns out, though, that like pop stars ranging from Madonna on back to Chuck Berry, Ke$ha wants it both ways: mass-audience success and artistic acknowledgment. For Ke$ha, that's what her album title Warrior means: She's fighting a war on multiple fronts.

Tracey Thorn's interpretation of "Maybe This Christmas," by the Canadian singer-songwriter Ron Sexsmith, is typical of her new holiday album, Tinsel and Lights: It's simply arranged, emphasizing Thorn's lovely, delicate voice and bolstered by a firm intelligence; it avoids the fatty treacle that weighs down lots of Christmas albums. Tinsel and Lights mixes familiar songs with new ones, such as the title song written by Thorn.
