Shania Twain, Album: Essentials: Perhaps the perfect example of an artist cutting their teeth in the world of country before transitioning to pop, Shania Twain is one of the biggest crossover successes of all time. Emerging in '93 with an attention grabbing self-titled debut, Twain's sound constantly developed over the years, with her ascent to worldwide stardom truly kicking in around the mid-'90s. Third LP, Come On Over, securely marked her place in history, becoming the biggest selling country album ever. Twain embarked on a hiatus in '04 but returned to the stage in '12 for a long-running Las Vegas residency.
