Miranda Lambert may be a blonde who sings country music, but I wouldn’t try grouping the gun-loving Texan in with her fellow fairly-follicled females — her spitfire style demands a category of its own. (Also, she might shoot you.) Here’s what’s great about her upcoming third album, Revolution, out Sept. 29: the “Crazy Ex-Girlfriend” singer has toned down the fury and upped the maturity with grown-up, thoughtful tunes like “Love Song,” which she wrote with Lady Antebellum’s Charles Kelley and Dave Haywood. Speaking of, look! Down there! It’s Miranda Lambert singing “Love Song,” exclusively for you, Mixers! Check it out after the jump, and let us know in the comments what you think of our little Lambert, all growed up.
