WSJ News Exclusive | For Music-Rights Deals, the Hits Keep Coming

And they’re not done: The firm has more than $1 billion available to keep buying, according to people familiar with the matter, an indication that the hot market for music intellectual property will continue.

A flurry of high-profile deals late last year revealed a frenzied market for music copyrights, whose popularity has exploded thanks to streaming, low interest rates, and copyrights’ steady returns. Megadeals for Stevie Nicks’s and Bob Dylan’s songwriting copyrights have prompted many more artists to look at their catalogs and consider sales while investors are eager to spend. Many legacy artists have rushed to close transactions before an expected increase in capital-gains taxes by the Biden administration, executives and lawyers say.

& Co. joined the fray with an investment in producer Ryan Tedder’s catalog of hits, including songs from Beyoncé, Adele and Stevie Wonder.

“It is competitive, but we still see good value,” said Tempo Chief Executive Josh Empson. “What excites us are the strong tailwinds: the continued shift to a rental economy for content, the growth of audio consumption as a category, and the continued globalization of the streaming platforms.”

Data from the rise of music streaming has allowed investors to map out highly calculated estimates of catalogs’ worth.

“We also believe that there is now an opportunity to underwrite these assets with greater precision than has been possible in the past,” Mr. Empson said.

Tempo launched with $650 million in funding from Providence Equity Partners, one of the private-equity industry’s oldest firms focusing on media and information services. Together with Warner Music, it aims to be a platform for promoting and making money from the work of top artists. Its first acquisitions included copyrights from star songwriters Jeff Bhasker, Shane McAnally and Ben Rector.

New additions include copyrights from Brett James, whose credits include No. 1 hits for Carrie Underwood, Kenny Chesney and Jason Aldean; popular Christian music singer-songwriter Mia Fieldes; Bruno Mars and Adele producer Philip Lawrence; and Frank Ocean collaborator Malay.

Some music executives have warned that there are only so many top-tier catalogs left worth investing in. And there’s debate within the industry over whether these music acquisitions—many fetching upward of 20 times annual earnings—will pay off and over what time frame.

But many executives say the opportunity for music to make money is only just taking off as global markets come online with streaming and catalogs are licensed for use across social media, videogames and fitness apps.

“These prolific writers and performers have devoted fan bases, and in addition to the catalog assets we have acquired, hopefully we can all count on them to produce exciting new work for many years to come,” Mr. Empson said.
