In "Move Your Body," Beyonce and her cohorts wave the American flag. In her latest song release, the singer salutes it.

The pop star has covered "God Bless the U.S.A." for charity, for the New York Police & Fire Widows' & Children's Benefit Fund. The track was unveiled on CNN's "Piers Morgan Tonight" and promptly went up for sale on iTunes.

The original version of the song first appeared in 1984, sung by country artist Lee Greenwood. It made a resurgence in popularity after the first Gulf War and after the attacks on Sept. 11, 2001.

Beyonce's been quite productive lately, with her "Body" campaign and single push, plus "Girls (Who Run the World)," from her new album.

After five years as a columnist and editor at Billboard, Katie Hasty joined HitFix in 2009 for music and film reporting out of New York. The Midwest native has worked as a writer, music promoter and in A&R since 1999 and performs with her band Numbers And Letters.
