Here are a few key aspects of watermarked songs:

1. Copyright Protection: One of the primary purposes of watermarking songs is to protect copyright. Record labels, artists, and content creators may embed watermarks in their music to deter unauthorized distribution and sharing. These watermarks can be hidden in the audio data and serve as a traceable identifier.
2. Ownership and Licensing: Watermarked songs can help in tracking the ownership and licensing of music. When music is licensed for use in various media (e.g., films, advertisements, television shows), watermarks can be used to ensure that the appropriate rights holders are compensated for their work.
3. Anti-Piracy: Watermarked songs can discourage piracy and unauthorized distribution. If a watermarked song is leaked or shared without permission, the watermark can be used to trace the source of the leak and identify the responsible party.
4. Monitoring and Detection: Music streaming platforms and content distribution services may use watermarks to monitor their content and detect copyright infringement. Automated systems can scan uploaded audio files for watermarks to ensure compliance with licensing agreements.
5. Authentication: In some cases, watermarks can be used to authenticate the legitimacy of a song or its source. For example, it can help verify that a particular recording is an official release from an artist or record label.
6. Metadata: Watermarks can also carry metadata information such as copyright details, usage rights, and contact information for the copyright owner, making it easier to manage and license music.

It's worth noting that watermarks are typically designed to be imperceptible to the listener, so the audio quality of the song is not significantly affected. However, they can be detected and decoded by specialized software and equipment when necessary.

Overall, watermarked songs play a crucial role in protecting the rights and interests of content creators and copyright holders in the digital age.
