Girl Groups to Olivia Dean: Music Insiders Predict 2026's Hottest Hits

The music industry is on the brink of a transformative year, with a mix of nostalgic sounds, technological debates, and familiar names set to shape the mainstream landscape in 2026. Industry insiders suggest that the coming year will be marked by heightened competition as record labels, streaming platforms, and artists navigate the balance between innovation and the resurgence of past trends.

Nostalgia Makes a Comeback

One of the most anticipated trends for 2026 is the return of early 2000s-era music. Karen Pettyjohn, head of U.S. programming at Amazon Music, highlights that nostalgia is making its way back into the music world, especially in pop genres. "There are lots of nods to that millennial era pop," she explains. This trend extends beyond just K-pop, with an increasing number of labels launching new groups that reflect this style.

A clear example of this trend can be seen in the release of two Netflix competition shows in 2025: "Simon Cowell: The Next Act" and "Building the Band." Both focus on creating the next big music group sensation. Additionally, the K-pop influenced girl group Katseye made a significant impact this year, earning two Grammy nominations and being named TikTok's Global Artist of the Year.

Olivia Dean and Big Name Releases

Another key prediction for 2026 is the dominance of Olivia Dean on the charts, alongside a wave of major releases from well-known artists. Tom Poleman, iHeartMedia's chief programming officer, believes that Olivia Dean will be one of the biggest breakout artists of the year. He also anticipates new releases from a wide array of artists, including Olivia Rodrigo, Harry Styles, Bruno Mars, Luke Combs, Nicki Minaj, Charli XCX, Noah Kahan, and BTS.

Poleman emphasizes the importance of what he calls a "consensus song" — a track that is universally loved across multiple formats. As the industry looks ahead, there is a growing hope for music that resonates with a broad audience.

AI in Music: A Debate

The role of artificial intelligence (AI) in music is expected to spark intense debate in 2026. Tom Poleman of iHeartRadio has taken a firm stance against AI-created music, stating that his platform will not support such content. "We don't play them on our radio stations, and we don't play them on the iHeartRadio app," he says. Poleman argues that AI lacks soul and a heartbeat, which he believes are essential elements of music.

Spotify, on the other hand, is taking a different approach. The company is working to protect artists from the misuse of AI tools, such as spam, impersonation, and deception. Sam Duboff, global head of marketing and policy for music business at Spotify, states that the company aims to ensure strong systems are in place to prevent bad actors from overshadowing authentic artists. "We're going to follow the lead of artists and the music industry, see how they're using AI tech, and we'll plan to evolve our protections, our policies, alongside them," he adds.

The Influence of Listeners

Ultimately, the music that listeners hear through their headphones is shaped by their preferences and interests. Karen Pettyjohn emphasizes that her team is always customer-obsessed, focusing on what customers are looking at and interested in connecting with. "We follow their lead," she says, highlighting the importance of listener feedback in shaping the future of music.

As 2026 approaches, the music industry is poised for a year of change, where the past and future will collide in unexpected ways. Whether it's through the return of 2000s sonics, the rise of new artists, or the ongoing debate around AI, the coming year promises to be an exciting chapter in the evolution of music.
