In an exclusive interview with PEOPLE, the singer, 59, opens up about how she has never allowed herself to be contained within the music industry, by executives and fans alike.
"If I feel like I'm being put in a box, I start to panic," Twain, who stars in a Coffee mate ad for the 2025 Super Bowl, says. "I run in any direction I can because I don't want to be contained. I have to be able to find my own way."
"Sometimes I'm not even sure where I'm going myself. How can somebody else tell me that, right? So I need the freedom to explore and to land wherever that exploration takes me," she adds.
Twain's music career began in April 1993, when she released her self-titled debut album, though it was a commercial flop.
The star later rose to fame with her second studio album, 1995's The Woman in Me, which featured hit country singles including "Any Man of Mine" and "Whose Bed Have Your Boots Been Under?"
Two years later, Twain released her follow-up album, Come on Over, including hit singles that showed off more of her pop side and cemented her as a crossover artist, such as "You're Still the One," From This Moment on," "That Don't Impress Me Much" and "Man! I Feel Like a Woman!"
Up!, released in 2002, did the same, with singles including "I'm Gonna Getcha Good!" and "Forever and for Always."
Twain later went on to release Now (2017) and Queen of Me (2023) and has toured across the globe, as well as taken part in numerous Las Vegas residencies.
Over the course of her illustrious career, Twain has received five Grammy Awards, two World Music Awards and 39 BMI Songwriter Awards, as well as inductions into Canada's Walk of Fame and the Hollywood Walk of Fame, plus the Canadian Music Hall of Fame and Nashville Songwriters Hall of Fame.
According to Twain, getting to experiment with music genres throughout her career allowed her to play by her own rules and not those of another. "If somebody's already dictating that, it just ruins it all for me. It spoils the fun and it kills the passion of the creativity that I'm creating as I go," she explains. "If that gets interrupted, I think you really kill the spirit of the artist."
Looking at other musicians who have refused to be contained to one genre — including Beyoncé, who recently released her country album, Cowboy Carter, and won album of the year for it at the 2025 Grammys — Twain tells PEOPLE "It's really great to see."
"I'm always championing anybody that does things that are unexpected by the industry, or unexpected by the audience," she continues. "They may not have seen it coming, but the artist does have a sense of where they want to go exploring, and I really think it's wonderful that they do, that they explore it, and they take it to whatever limit interests them."
"We get bored too, if we're not allowed to stay open and channel things outside of what would be considered our normal or what's expected of us," adds the mother of one.
"It is very moving," Twain says, "and I relate to what they say when they talk about me and how they're feeling and how they express it to me personally.
"I relate to it in the sense that I felt that way when I was younger about other artists that had already been where I was headed, or where I was dreaming about being and what I was aspiring to become, and how I felt in my heart and my mind of what I would say if I had ever had the chance to meet them," she continues.
Adds the "Man! I Feel Like a Woman" musician: "So I can imagine that is what they're feeling in those moments."
Over the years, Twain has received praise from many younger stars in the music scene across genres.
A year later, in April 2022, Styles, 31, brought Twain out as a surprise guest during his headlining Coachella set, where he admitted he was "starstruck" to be sharing the stage with her, adding, "This lady taught me to sing. She also taught me that men are trash."
According to Twain, "It is very humbling and it's rewarding" to see the impact she has made on musicians who have come after her.
She adds that the praise she gets from younger artists makes her look back at her time as a newcomer within the music scene too.
"I feel like, well, maybe that's what I would have said if I'd met certain people and had the chance to say what I really wanted to say or to perform with them," Twain explains.
Still, the mother of one notes that she has had her chances over the years to extend her own gratitude to those she admires in her life.
"I have had a chance to do that on several occasions. I've had the opportunity to give gratitude to those who I've looked up to," Twain — who stars in a Coffee mate ad for the 2025 Super Bowl — says.
In an exclusive interview with PEOPLE, the singer, 59, recalls performing during the Super Bowl XXXVII halftime show in 2003.
"That was a really exciting moment," Twain recalls. "I think I was quite numb. I can remember feeling a little like I was in a tunnel or something. It was such an overwhelming and chaotic environment around me."
Detailing that "the whole stage had to be put out there in a matter of minutes," the star continues, "Everybody had to be transported out there in this big convoy — the band, technicians, instruments, everything — in a very short period of time, so we had to actually rehearse the timing of it more than we rehearsed the music, because it's live TV time. It's got to be exactly on cue and everything's got to be on time."
During the halftime set, Twain was joined at the San Diego Stadium (then the Qualcomm Stadium) in the California city by No Doubt and Sting.
Twain opened the show with her iconic song "Man! I Feel like a Woman!" before she performed her then-new song "Up!"
No Doubt then appeared onstage together to sing their hit "Just a Girl." During the performance, lead singer Gwen Stefani ad-libbed lines, including, "I'm just a girl at the Super Bowl."
Sting then concluded the set by performing The Police's track "Message in a Bottle," with Stefani, 55, joining midway through.
Continuing to look back at her halftime set, Twain tells PEOPLE the performance, overall, "went by really fast, and I don't think I absorbed it in the moment."
Still, the "Waking Up Dreaming" musician says she will "get a lot of pleasure" when she thinks about the show, adding, "I was part of a much bigger thing than a Shania performance. It was massive."
This year, Twain stars in a new commercial for Coffee mate, in which she plays a singing version of a tongue to promote the brand's cold foam creamers. Kendrick Lamar will headline the 2025 Super Bowl halftime show, with SZA as a special guest.
Super Bowl LIX — where the Kansas City Chiefs will face off against the Philadelphia Eagles at the Caesars Superdome in New Orleans — will take place on Sunday, Feb. 9.
