Los Lonely Boys and Gretchen Wilson have struck digital platinum with the RIAA. Los Lonely Boys’ “Heaven” was simultaneously certified gold (for 100,000 legal downloads) and platinum (for 200,000 downloads). Downloads of Wilson’s music resulted in gold certification for “Here for the Party” and platinum status for “Redneck Woman.” Other singles going digital gold in the latest round of certifications officially announced by the RIAA include Shania Twain’s “Party for Two,” Lee Ann Womack’s “I Hope You Dance” and Lynyrd Skynyrd’s ’70s hit, “Sweet Home Alabama.” During last week’s CMA Music Festival, Mercury Records executives said downloads of Sugarland’s debut single, “Baby Girl,” have also qualified them for a gold single. … In other RIAA certifications, Blake Shelton’s Barn & Grill netted two certifications — gold album (for 500,000 units shipped) and gold long form video (50,000) units shipped. As previously reported, Sugarland’s Twice the Speed of Life album was certified gold, and Rascal Flatts’ Feels Like Today went double platinum (for 2 million copies shipped).
