For over a century, the music industry revolved around a simple idea: selling physical copies of recordings. It started with Thomas Edison's phonograph, which led to fragile shellac records, and eventually, the durable vinyl LPs that dominated the mid-20th century. Each new format shifted how people listened. The rise of the album in the 1960s turned music from a single-song experience into a cohesive artistic statement.

Cassette tapes and CDs followed, making music portable and personal. For decades, the business model was straightforward: record an album, manufacture copies, ship them to stores, and promote them on the radio. The entire industry was built on controlling the production and distribution of these physical objects.

Then, the internet arrived. Peer-to-peer file-sharing services like Napster dismantled this model in a few short years by making music infinitely copyable and free. The industry's response was digital storefronts like iTunes, which re-established a way to sell music, but the shift was profound. Scarcity was gone, and the industry had to find a new way forward.

Even as technology changes, the core roles within the music industry remain largely the same. Understanding who does what is key to seeing how the whole system works. It’s a network of specialists, each handling a different part of a song's journey from an idea to a listener's ears.

Let’s break down these roles.

Artists are the creators. They write, compose, and perform the music. They are the origin of the entire process.

Record Labels are the investors and project managers. They sign artists and fund the recording process, marketing, and promotion. In exchange, they typically own the master recordings and take a significant share of the revenue. Labels range from massive corporations (the 'majors') to small, independent operations.

Publishers handle the business of the song itself, known as the composition. This includes the lyrics and melody, separate from any specific recording. They license the compositions for use in movies, commercials, or by other artists and ensure the original songwriters are paid royalties.

Distributors are the logistics experts. Traditionally, they moved physical products like CDs to retail stores. Today, their primary job is to deliver digital music files to hundreds of online stores and streaming services, like Spotify and Apple Music, and to collect the earnings from them.

The music industry has several distinct income sources. While the methods have evolved from physical to digital, the fundamental categories of revenue have been surprisingly consistent.

For much of history, physical sales were the main engine of the industry. Now, streaming is the dominant source of revenue, but it works very differently. Instead of a one-time purchase, artists and labels earn a fraction of a cent each time a song is played. This has fundamentally changed the economics of being a musician.

This basic structure—creators, investors, publishers, and distributors—forms the foundation of the music business. While new technologies continue to reshape the landscape, these core functions and revenue streams remain central to how music is made and sold.
