Nielsen SoundScan has awarded Taylor Swift for having the best selling debut week for a female country artist.

First week sales for her 'Speak Now' album were 1,047,000 making it the biggest selling debut for a female country artist ever.

Taylor Swift album sales in 2010 added up to around 4.4 million. She has sold over 4 million albums a year for the past three years and had it not been for Michael Jackson's death in 2009, she would have been the biggest selling artist of that year as well.

Taylor is also the top selling digital artist of all-time. 34,269,000 Taylor tracks have been downloaded, according to Nielsen SoundScan.

Taylor Swift was also the most played artist on US radio with 1,128,100 spins registered last year, according to Nielsen BDS.

BRITNEY SPEARS - Hold It Against Me (OFFICIAL NEW SINGLE)

"Hold It Against Me," the hotly anticipated new Britney Spears single, inevitably arrived on the Web a day ahead of its scheduled release, with Spears writing on Twitter, "Don't #HOLDITAGAINSTME for coming out early." It's easy to see why the pop star didn't want to wait: with its throbbing bassline and pulsating kick drum, this Max Martin/Dr. Luke mind-meld is in a hurry to get where it's going. The track's balance between club-ready verses and a soaring pop chorus (which melodically recalls the verse from Dido's "Thank You" sampled in Eminem's "Stan") is more reminiscent of the Black Eyed Peas' recent hits than anything in Brit's formidable singles catalog. While lyrics like, "If I want your body now/Would you hold it against me?" don't earn points for originality, "Hold It Against Me" is a winner and a tantalizing teaser of Spears' forthcoming, still-untitled album, due in March.

Trey Songz Planning New Album for 2011

Even as his latest album, "Passion, Pain & Pleasure," continues to churn out singles -- including the latest, "Love Faces" -- Trey Songz is hatching plans for its successor. 

"I want to release an album this year," the Atlanta-based R&B singer tells Billboard.com. "We're starting in the studio now. I'm always thinking about music. I'm in the studio whenever I can be. I'm not pressed or in a rush to make an album right now, but I always have a need to make music."

Sisters Shelby Lynne, Allison Moorer to Release Collaborative Album

After a prolific 2010, sisters Shelby Lynne and Allison Moorerplan to record their first collaborative album this year.

"We're starting to write in March and hopefully we'll put out a record next year," Lynne tells. "We're going into uncharted territory here. We'll see what happens. I expect it to be really good and really soulful. We're just a couple of singers who happen to be sisters...getting together to write songs and see what we can do together."

The album is an outgrowth of a tour the two did late last year, which Lynne says was an "excellent" experience for all concerned. "We loved it, people loved it," she reports. "It was just the two of us on two guitars. Having not written anything yet we did each other's songs and reached back into our childhood and grabbed a couple of things that we grew up singing. It worked brilliantly. We both like to tell stories and cut up and have fun and go with the flow...We don't fight. I know everybody would love that to be the case, but that's not the way it is, and I don't see anything like that happening."

Lynne is coming off a 2010 in which she released her 11th studio album, "Tears, Lies and Alibis," as well as her "Merry Christmas" collection, both on her own Everso Records imprint. Moorer, meanwhile, released her own album, "Crows."
