Brenda Lee’s ‘Rockin’ Around the Christmas Tree’ Re-Released in Spanish Using AI Technology

A new Spanish-language version of Brenda Lee‘s holiday hit “Rockin’ Around The Christmas Tree” was released Friday (Oct. 25), using “responsibly-trained” artificial intelligence to make the translation. A perennial hit for 66 years and counting, “Rockin’ Around The Christmas Tree” is the biggest song to have been translated into a new language using AI.

Released via MCA Nashville/Universal Music Enterprises (UMe), “Noche Buena y Navidad” was revamped by four-time Latin Grammy award-winning producer Auero Baqueiro. Baqueiro first translated the lyrics from English to Spanish, trying to match the same phonetics and rhyming structure that made sense for Spanish while maintaining the original lyrical themes from the original English version. Then, he enlisted Chile-born, L.A.-based vocalist Leyla Hoyle to sing the vocals in Spanish in a way that would capture Lee’s unique voice patterns, including intricacies like phrasing, tone, and breaths.

Baquiero ultimately kept the original music and background vocals and, once Hoyle recorded the raw Spanish vocals, used AI to map Lee’s voice over Hoyle’s performance. The translation was made possible using SoundLabs AI’s MicDrop technology, a “responsibly-trained” AI audio plugin that allows users to swap their voices out with another voice or instrument.

The new AI-powered translation arrives just in time for the holiday season. Despite being released back in 1958, Lee’s “Rockin’ Around the Christmas Tree” is more popular than ever. Last year, her song hit No. 1 on the Billboard Hot 100 for the first time and stayed in the top spot for three straight weeks.

Lee is not the first artist to use AI to translate her work. In May 2023, HYBE debuted a new K-pop artist, MIDNATT, who used AI to release his first single in six different languages. In November 2023, indie-pop artist Lauv released an AI translation of his single “Love U Like That” in Korean as a nod to his strong fanbase in that country. Similarly to “Rockin’ Around the Christmas Tree,” a bilingual human songwriter, Kevin Woo, translated the “Love U Like That” lyrics to Korean. After Woo sang through the song, Lauv’s voice was planted on top of his vocals using the AI voice platform Hooky.

Finally, country icon Randy Travis made headlines in May 2024 by using AI voice technology to record a new single, “Where That Came From,” after his vocal abilities were greatly diminished in a near-fatal stroke a decade before.

The Spanish-language version of “Rockin’ Around the Christmas Tree” is the first release from Universal Music Group (UMG) and SoundLabs’ partnership, which was announced in June 2024. The AI company was founded by software developer and electronic artist BT and is said to be “responsibly” trained. The partnership is part of UMG’s “responsible AI initiative,” as laid out by the company’s CEO/chairman Lucian Grainge, which involves “forg[ing] groundbreaking private-sector partnerships with AI technology companies.”

“I am so blown away by this new Spanish version of ‘Rockin’ Around The Christmas Tree,’ which was created with the help of AI,” said Lee in a statement. “Throughout my career, I performed and recorded many songs in different languages, but I never recorded ‘Rockin’’ in Spanish, which I would have loved to do. To have this out now is pretty incredible, and I’m happy to introduce the song to fans in a new way.”

“We are thrilled to work with Brenda Lee to making ‘Rockin’ Around The Christmas Tree’ the first classic song translated responsibly into another language with the power of AI, added UMe president/CEO Bruce Resnikoff. “We are also very excited about the possibilities of this emerging technology and look forward to harnessing its capabilities to introduce new material created by and approved by our artists.”

“The minute you hear Brenda Lee’s iconic voice on ‘Rockin’ Around The Christmas Tree’ you know it’s the official start of Christmas,” said UMG Nashville chair/CEO Cindy Mabe. “The global hit has touched people all over the world and kept this young 13-year-old spirit of Christmas captured in a time capsule. We are all so excited for this new Spanish version created with the help of AI from that legendary voice and approved by Brenda Lee herself to help celebrate this enduring, timeless classic.”
