With 2010 half over, we pause to take a glance at some of the top selling albums and songs of the year so far and how they stack up compared to where we were a year ago.

Thanks to Eminem's recently released "Recovery," we squeak by with five albums having sold at least a million copies this year, according to Nielsen SoundScan, through the week ending July 4.

Lady Antebellum's "Need You Now" is the year's biggest so far with 2.4 million, while Justin Bieber's "My World 2.0" is in second with 1.4 million and Sade's "Soldier of Love" is third with a little over 1.2 million. Lady Gaga's "The Fame" is in fourth with 1.2 million. "Recovery" has moved 1.1 million in just two weeks' time, placing it at No. 5 on the mid-year best selling albums tally.

A year ago at this point, four albums had shifted more than a million, and two of them were also by Eminem and Gaga. Em's last release, "Relapse," was the third-best seller with 1.2 million, while Gaga's "The Fame" was fourth with 1 million. Taylor Swift's "Fearless" was tops with 1.4 million and the "Hannah Montana: The Movie" soundtrack was second with a little over 1.2 million.

Lady Antebellum's "Need You Now" also naturally reigns as the year's best selling country set, while Sade's "Soldier of Love" is the biggest R&B/hip-hop album. Eminem's "Recovery" is tops among rap efforts, while Jack Johnson's "To The Sea" (481,000) is the biggest rock album. Rounding out the genre run down, Aventura's "The Last" is the largest seller among Latin albums (100,000) while Kings of Leon's "Only By The Night" is the best selling catalog title (248,000).

Year to date album sales stand at 154.0 million, down 11% compared to the same total at this point last year (172.9 million).

2010's best selling digital song is Train's "Hey, Soul Sister," with 3.4 million, making it the only tune to shift more than 3 million this year. Another 13 tracks sold more than 2 million each. At this point last year, three songs had moved more than 3 million -- Flo Rida's "Right Round" (3.6 million), Lady Gaga's "Poker Face" (3.4 million) and the Black Eyed Peas' "Boom Boom Pow" (3.3 million) -- while another five had done more than 2 million apiece.

Year to date track sales are at 597.4 million, down less than 1% compared to the same total at this point last year (598.9 million).
