After years of decline, music industry revenue has surged to its highest level in more than 20 years. The reason? Music streaming companies like Spotify.

While physical and digital music sales have continued to wane, audio streaming has exploded over the last seven years and now accounts for over $15 billion of music industry revenue. Moreover, Spotify isn't satisfied with just delivering great music to its users. The company has invested in podcasts and audiobooks, landing exclusive deals with celebrities as varied as Joe Rogan and Meghan Markle.

Operationally, the company is firing on all cylinders. In its most recent quarterly report, Spotify announced a 19% year-over-year increase in daily average users (DAUs) to 433 million and a 14% jump in paid subscribers to 188 million. The company is expanding its international user base, and it specifically called out blistering growth among Gen Z users in Latin America. Just as video streaming disrupted traditional TV and movies, streaming has done the same to audio. Smart investors should take note and load up on Spotify shares now.
