Jem Aswad Senior Music Editor Warner Chappell Music has renewed its global publishing deal with producer Marco “MAG” Borrero. A frequent Bad Bunny collaborator, MAG produced 15 of the 23 tracks on the blockbuster album “Un Verano Sin Ti,” which led to his 2022 Variety Hitmakers honor and his No. 1 position on Billboard’s Year-End Hot Latin Song Producers chart. “Un Verano Sin Ti” became the first all-Spanish album to top the year-end Billboard 200 chart as well as earn a nomination for Album of the Year Grammy award. The Brooklyn-born, Puerto Rican-Dominican producer was mentored by Max Martin — the most successful songwriter-producer of the past 25 years — and over the course of his career has also collaborated with Rauw Alejandro, Arcángel, Bebe Rexha, Imagine Dragons, Selena Gomez, and Demi Lovato.
