It is illegal and unethical to use any technology to cover up the original source of a song in order to use music without permission. This behavior seriously infringes on the legitimate rights and interests of music creators and copyright owners, and undermines the healthy ecology of the music industry. The normal operation of the music industry depends on creators being able to obtain reasonable returns through legal authorized use, thereby motivating them to continue to create excellent works. There are special audio analysis and recognition technologies on the Internet that can accurately detect the source of music. It is difficult to succeed in trying to cover up the original source through technical means to evade supervision. Once discovered, they will face legal responsibilities and serious consequences, including high fines and legal proceedings. We should always abide by laws and regulations, respect music copyrights, and obtain and use music through legal channels.
