While Britney Spears has always opted for shiny pop tunes, her baby sister, Jamie Lynn Spears, is taking a different musical path. She has just released her twangy country ballad, "How Could I Want More."

The track — full of acoustic guitar and Nashville flourishes — plays up Spears' strong country vocals, which are reminiscent of Carrie Underwood. On the track, a tease for her forthcoming debut album, the 22-year-old sings about being in a relationship with a guy who treats her like a princess and swears he loves her. And while she has some reservations, in the end, she realizes "how could I want more?" even if things aren't always perfect.

Jaime Lynn has yet to announce when she will release her album. In an interview with E! News earlier this month, she opened up about finally giving fans her music, which she has been working on for several years after a part-time move to Nashville. This album marks her return to the scene after giving birth to her daughter Maddie in 2008 and leaving her Nick show, "Zoey 101."

"I think that now it's like real. It's like being like 'Oh my gosh! I'm going to have a baby.' It's seeing it all here and it's real," she told E! News earlier this month of her music. "It's like, 'Oh my goodness, I'm really gonna do this.' And it is; it is. It's like my second baby."

In addition to this new track, she will also appear on Britney's December 3 album release, Britney Jean, on the song "Chillin' With You."
