Record labels publish and market music recordings and videos. There are major labels like Universal Music Group, Sony Music Entertainment, and Warner Music Group. Independent labels are not affiliated with major labels and are considered more artist-friendly, though they have less financial resources. Record labels provide financial support for recording, mixing, mastering, pressing, and marketing albums. They earn back this investment if albums are successful. Copyright law restricts unauthorized use of music and record labels are responsible for controlling use of the music they publish and enforcing copyright.
