LeAnn Rimes got her start at the tender age of 13, and in 1996 she became the youngest country star since Tanya Tucker more than two decades before. While I knew Rimes had been around a while, I had no idea she had been so prolific—at age 30, she already has 15 albums under her belt. Over the past two decades Rimes has veered from her country roots in favor of more traditional pop, but whichever style she adopts, her voice is always up to the task. That and her sense of adventure with each release is what has always set Rimes apart from the Faith Hills and Shania Twains. MARK LORE
