theoretically, you have no right to edit other people's songs. Even if you don't make a profit, you don't have this right. You edit it quietly at home, no one knows, it's okay. But what you publish is tantamount to modifying other people's works without authorization, which violates the laws and regulations on copyright protection.

For a simple analogy, when the rising sun sang Wang Feng's songs, Wang Feng's lawyer later talked with them about the copyright fees. Even if the rising sun masculine sings for free and is not profitable, it also infringes the copyright of Wang Feng.

To put it another way, Rising Sun Masculine is not profitable, but they don't charge advertisers for advertising in the Spring Festival Evening when they sing.

when you upload it to a video website, you are not profitable, but the video website is profitable.

However, the copyright protection in China is very backward. Nobody cares about this matter. You are well-intentioned. If the original singer won't bother you, there will be no legal investigation.
