Autographed Platinum Edition Album of Lady Antebellum. According to a recent article in NASHVILLE SKYLINE: Lady Antebellum carry country music these days. They've come to the rescue of a sputtering music genre. One year ago, Taylor Swift was the best-selling recording artist in the world. Now, who is? Maybe Justin Bieber or Lady Gaga? It does not come as any great surprise that it's Lady Antebellum. Their Need You Now is the best-selling album in all music genres in the world for the first half of this year. In just the first six months of this year, the trio's album Need You Now has sold almost 2.4 million physical copies, according to Nielsen Soundscan. It has impressively outpaced Bieber's nearly 1.4 million sales of his CD My World 2.0. Need You Now was released Jan. 26. In the first three months of this year, it sold 1.6 million copies. In the past three months, it accounted for another 708,000 copies sold -- even as overall CD sales in all music genres continue to drop. Additionally, digital downloads of the single "Need You Now" have reached 2.1 million copies. July 15, 2010; Written by Chet Flippo.
