Taylor Swift's years-long campaign to regain control of her music has entered another unexpected chapter after a new publishing partnership involving longtime collaborators Max Martin and Shellback raised fresh questions about the ownership and future licensing of some of the biggest songs in her catalog. The development comes as reports continue to circulate that Swift and Kansas City Chiefs star Travis Kelce are preparing for a wedding celebration in New York, adding another layer of public attention to one of the entertainment industry's most closely watched figures.
The new agreement centers on Swedish hitmakers Max Martin and Shellback, along with their Wolf Cousins songwriting collective, which has entered into a publishing partnership with HarbourView Equity Partners. Although the financial terms have not been officially disclosed, entertainment attorney Bradfield Biggers said the transaction appears to give HarbourView an economic interest in a collection of songs written or co-written by the producers and their collaborators.
According to Biggers, the agreement does not affect Swift's ownership of her master recordings, which she famously regained after years of public disputes over the rights to her early music. Instead, the deal involves publishing rights connected to the underlying musical compositions, an important distinction in the music business because commercial licensing typically requires approval from both the owner of the master recording and the owners of the composition.
That distinction could prove significant for film, television, advertising and commercial partnerships involving songs written jointly by Swift, Martin and Shellback. If HarbourView now controls or shares publishing rights in some of those compositions, the investment firm could potentially participate in licensing decisions alongside other rights holders. Based on publicly available information, however, there is no indication that Swift has lost ownership of her recordings or control over her catalog as a whole.
Among the songs reportedly connected to the Wolf Cousins catalog are "Style" from 1989 and "...Ready for It?" from Reputation. The complete list of works included in the transaction has not been released publicly, and the precise scope of HarbourView's rights has not been independently verified. As a result, many details surrounding the agreement remain unclear.
HarbourView Chief Executive Sherrese Clarke praised the partnership in a statement, calling Martin and Shellback "some of the most influential hitmakers in modern music." She added that Wolf Cousins had built "an extraordinary creative ecosystem spanning generations and genres," saying the firm was "proud to partner with them and help steward the legacy of this remarkable catalog."
The latest development inevitably draws renewed attention to Swift's long-running battle over music ownership. After Big Machine Records sold the master recordings of her first six studio albums in 2019, Swift publicly criticized the transaction and ultimately launched her "Taylor's Version" project, re-recording her catalog to regain commercial control. In May 2025, Swift announced she had successfully reacquired ownership of her original masters, describing the achievement as deeply emotional.
At the time, Swift said she had been "bursting into tears of joy at random intervals" after learning the agreement had been completed. She added that "all of the music I've ever made ... now belongs... to me," a milestone many artists viewed as one of the most significant ownership victories in modern music history.
