When Shania Twain released The Woman in Me in 1995, she had no idea how much that album would impact the rest of her life, or revolutionize country music as a genre. Eight singles were released from the record, including “Any Man of Mine,” “Whose Bed Have Your Boots Been Under” and “No One Needs to Know,” among others, with some finding a place on the pop charts as well. After Shania’s eponymous freshman debut failed to have any hit singles, the success of The Woman in Me was a surprise to everyone, including Shania, who was suddenly one of the most in-demand artists in the world, of any genre.

“I certainly had no idea during the making of The Woman In Me that it would be such a pivotal moment in my life and in my career,” Shania told Fox News. “It changed everything. I had no idea what to expect as far as if it would succeed at all and then when it did start to succeed, of course [I had] no idea that it would come to this — 25 years later I would be celebrating a diamond edition.”

“I’m just really grateful,” she continued. “At the time, when it was happening, when I was starting to experience success with that album, I got so busy that I couldn’t even celebrate the successes in the moment. So it’s only now that I’m really celebrating what was going on then.”

The Canadian just released The Woman in Me: Diamond Edition, in honor of the 25th anniversary of the record, which was certified diamond for sales in excess of ten million copies – a rare feat in country music.

“This is the album that changed my career and has brought me to places that I would never have imagined even in my wildest dreams at the time,” Shania told Good Morning America. “I had high hopes, but where I am today, 25 years later, at the time was unimaginable. So this is a real celebration year for me, celebrating coming out as a very independent, open minded, very bold in what I had to say.”

The Woman in Me: Diamond Edition includes “previously unreleased tracks, live recordings, and mixes that trace the evolution of an album that changed the way country music sounded,” a press release explained. 16 previously unreleased tracks, including five live versions, from her Zappos Theater at Planet Hollywood, Las Vegas residency, along with a “Shania Vocal Mix,” containing early takes of 11 songs from nearly a year before the The Woman in Me was released, are also included.
