Recorded music revenue expanded by 3.2 percent in 2015 worldwide to $15 billion (roughly Rs. 99,541 crores), fueled by an extraordinary growth in subscriptions to streaming services, according to the International Federation of the Phonographic Industry.
The growth is the first uptick in the music industry at a more than marginal level since 1998, when sales grew 4.8 percent year-on-year.
But the industry is still down by one-third since the late 1990s, when Internet service became mainstream in developed countries and listeners flocked to music sites, both legal and illicit.
The rapid growth of streaming services such as Spotify which allow unlimited, on-demand music online led digital music to surpass sagging physical sales for the first time last year.
The industry federation estimated that 68 million people around the world had digital subscriptions, compared with just eight million in 2010 when it started keeping track.
Streaming revenue grew by 45.2 percent in the past year alone, nearly matching sales from digital downloads on iTunes and other sites.
Yet the industry did not cast an entirely rosy picture, saying revenue was still far below potential.
"The value of music is still not being fully recognized. Today, there is a real spirit of optimism across our industry, but we are a long way from declaring 'mission accomplished'," Stu Bergen, the CEO for international and global commercial services at Warner Music Group, told reporters on a conference call.
Without singling out YouTube by name, the industry federation took aim at "user-upload platforms" as a persistent drain on the industry.
Some 900 million people essentially listen to music for free through advertising-supported sites, yet the revenue generated for the music industry is barely a quarter of that through streaming subscriptions, the annual report said.
Huge growth in China
The industry's growth came amid a massive spike in sales of licensed music in China, where revenue grew by nearly 64 percent.
But Edgar Berger, chairman and CEO of international for Sony Music, said that China should be one of the top markets for music consumption as it is for movies and not number 23 as at present.
"The biggest potential in the world for music growth is in China," Berger said.
The labels credited China's government with keeping its word on stepping up the legal framework against piracy.
But Frances Moore, chief executive of the music federation, voiced hope that China would also move ahead and set up its first system of performance rights, through which broadcasters pay to use songs.
Japan, Latin America also expand
The health of the music industry varied widely by country, the result not only of business trends but of the particular crop of local artists.
Japan, the largest market after the United States, saw music sales grow by three percent reversing several years of steep declines that contributed to dragging down the global industry.
The growth was the result in part of the introduction of streaming including Apple Music to Japan where, in sharp contrast to most of the world, some three-quarters of sales are CDs or, to an increasing extent, vinyl.
Latin America was the fastest-growing region, with revenue jumping 11.8 percent on soaring interest in streaming.
Argentina alone saw sales rise by more than one-third although Brazil, the region's largest country which has been beset by economic uncertainties, saw a small dip.
France and Germany were the other major markets that saw contractions, although in Italy sales jumped by 25 percent.
The music industry got a shot in the arm last year from British ballad singer Adele's "25," the fastest-selling album in years.
The album, which came out on November 20, sold 17.4 million copies worldwide in 2015, nearly five times as many as the runner-up, Ed Sheeran's "X," when not factoring in streaming, the industry group said.
