Shania Twain knows success -- especially success in multiple genres. Dubbed the Queen of Country Pop, Twain is one of the most commercially successful artists of all time. And she's applauding country-pop crossover Taylor Swift on her switch into the pop world.

"I think that everybody should just follow their heart and do their artistic best, and just enjoy their creativity," Twain tells ET Canada. "[Taylor]'s a singer-songwriter-performer, she does it all ... the world is her oyster. She's young and she needs to just do whatever she's having fun at and I think everybody's loving it."

The 49-year-old took her own advice on following her heart and retired from performing in 2004, eventually immersing herself back into life onstage through her critically acclaimed show 'Still the One' at the Colosseum at Caesars Palace in Las Vegas. Twain's time there will draw to a close in December, and she'll concentrate on the album she's promised fans and made good headway on. Excitingly, she's also looking at touring!

While Twain follows her heart back into the realm of country music, she knows what it's like to have the world as her oyster, and she readily supports Swift in her decision to move to 100 percent pop.

Fans are eagerly anticipating the 'Shake It Off' hitmaker's new album -- her first self-declared official pop record -- and according to one of the lucky attendees at her '1989' listening party, it's not just another pop record.

Journalist Chris Willman chronicled his experience listening to Swift's album on Twitter, hilariously writing, "Just heard @taylorswift13's album. It's not just 'more pop.' It's so gloriously pop, it makes 'I Knew You Were Trouble' sound like the Judds."

So ... there's that.

Swift's new album streets Oct. 27, and although it won't be filled with country delights like 'Tim McGraw' and 'Teardrops on My Guitar,' one thing's sure: she'll be having fun and following her heart.
