"I'm on the cusp of releasing new Spanish music this fall, I just filmed the two music videos for that," Aguilera told PEOPLE last month while speaking about her collaboration with SweeTARTS. "We had so much material, we're going to release it in six song segments episodically throughout the next year, because it really tells a story and it takes you on this journey and adventure, experiencing different pieces of my past. This is an illustration of my roots." Aguilera shared what looked to be snippet from one of the music videos to her Instagram just a few days ago. Christina Aguilera Has a 'Full Circle Moment' as She Performs at Disney World 50th Anniversary "It's a full-circle moment for me now, as a grown woman," she continued. "It's just so fulfilling to me now to dive into that, knowing what I know now after the career that I've had and being able to dive deeper into something that I'm so passionate about. Because sometimes, some of my most commercial successes were not my happiest moments. They weren't 100% true to me, or were my passion. But from the Stripped record on, I've always made music I fully believe in, even if it doesn't play into a specific pop box script. And this new album is that, personified." The "Genie in a Bottle" singer also discussed her musical tastes and how she loves collaborating with other artists. "I'm very, very eclectic in my musical taste," Aguilera told PEOPLE. "Bionic [her sixth album, released in 2010] was such an experimental record and I had so much fun doing it and recording it with artists from M.I.A to Sia to Santigold to Nicki Minaj to Ladytron; all these different, fun artists from such different musical worlds that I was able to combine together into this one album. It was amazing."
