Producer, songwriter and artist Metro Boomin – a.k.a. Leland Tyler Wayne – has sold a portion of his entire existing publishing catalog to Shamrock Capital for close to $70 million, sources close to the deal tell Billboard.

News of the sale arrives on the heels of his second album HEROES & VILLAINS, which was released on Dec. 2, 2022. The record was peppered with some of the biggest names in music, including features from Young Thug, Travis Scott, Future, Don Toliver, Chris Brown, A$AP Rocky, Gunna, and late Migos member Takeoff. The album debuted at No. 1 on the Billboard 200 albums chart, making it his second album in a row to hit No. 1 as an artist.

As one of rap and R&B’s most defining creatives, Metro Boomin has helped craft hits like “Bad and Boujee” by Migos, “Mask Off” by Future, “Congratulations” by Post Malone, “Bank Account” by 21 Savage, “Father Stretch My Hands, Pt. 1” by Kanye West, “Jumpman” by Drake and Future, “Heartless” by The Weeknd, “Waves” by Kanye West, “Child’s Play” by Drake, “Tuesday” by iLoveMakonnen, and many more.

The multi-hyphenate musician has had 99 total entries on the Hot 100 chart as a producer, including two No. 1s and 10 top 10s. As an artist, Metro Boomin has 46 total entries on the Hot 100. He has spent 18 weeks at No. 1 on the Rap Producers chart and three weeks at No. 1 on the Hot 100 Producers and Hot 100 Songwriters charts.

Representatives for Shamrock did not return Billboard’s requests for comment. A representative for Metro Boomin declined to comment.

Shamrock was founded in 1978 as Roy E. Disney’s family office and has since become an active, powerful buyer in the music catalog investment space. It’s most notable investment being that of Taylor Swift’s Big Machine catalog which the firm bought from Scooter Braun’s Ithaca Holdings in 2020. In 2021, Shamrock expanded into the lending space with a $196 million debt fund to loan money to IP owners in entertainment.

Last month, on Feb. 2, 2023, Shamrock Capital announced that it raised $600 million in a new fund (Shamrock Capital Content Fund III) aimed at acquiring film, TV, music video games, and sports rights.

Metro Boomin’s deal, along with other recent hip-hop acquisitions — like Juice WRLD’s sale to Opus Music Group for a nine figure sum, Dr. Dre’s Shamrock and UMG deal for an estimated over $200 million, and Future’s publishing catalog sale to Influence Media Partners between $65-75 million — have proved that the genre is fueling new investor interest.

Those who have been skeptical of rap catalog sales often point to the genre’s short history, which may indicate sharper — or still unknown — decay curves from other genres like rock and pop. Decay curves, which are based on past performance of other songs in the genre, refer to when the song levels out into a predictable state of income generation.

But the 50th anniversary of hip-hop special at the 2023 Grammy awards and its continued dominance on streaming platforms may reveal that rap is ready to become another sought-after genre for buyers.

“There are certain names that have been around for a long enough period that they are now of an evergreen standard,” City National entertainment banking leader Denise Colletta recently told Billboard. “Those household names in hip-hop will continue to resonate with audiences.”
