It is illegal to use copyrighted music without permission, regardless of whether it is trying to conceal its original source. Doing so not only violates the law, but may also cause economic losses to creators and copyright holders. Music creators and copyright holders rely on these rights to get their due remuneration, and unauthorized use will harm their interests. Even if certain techniques are used to mask the original source of the music, such as audio processing, mixing, or re-arranging, these behaviors may still be detected, especially if advanced audio recognition technology is used. In addition, an attempt to conceal the source of the music may itself be regarded as a further infringement of copyright, thereby increasing legal liability. If you wish to use a certain song, it is recommended that you obtain permission through legal means. You can contact the copyright holder or obtain a license through a legal music licensing platform. This will not only protect your legitimate rights and interests, but also respect and support the fruits of the labor of music creators. Respect for intellectual property rights and compliance with the law are the responsibilities and obligations of every citizen. The use of music through legal means is not only a respect for creators, but also an important way to maintain the healthy development of the entire music industry.
