Trending on Billboard In March, Universal Music Group chairman/CEO Lucian Grainge spoke with investors about his company’s $775 million acquisition of Downtown Music Group. The moment marked Grainge’s first comments since European regulators greenlit the deal, and the major-label mogul likened it to UMG’s $1.9 billion acquisition of EMI in 2011.  “Today, 15 years later, that acquisition is universally acknowledged as one of the most successful and strategically important in the history of the music industry,” Grainge said. “I firmly believe that our acquisition of Downtown will be as transformational.”  Related Downtown’s businesses — distributors FUGA and CD Baby and publishing administration platform Songtrust among them — will help UMG expand its offering and geographic footprint in the high-growth global indie segment, where UMG is third behind Sony’s The Orchard and Believe.  Nat Pastor and J.T.…
