If you had the rights to the lyrics of a musical work, you could first ask the singer for authorization. The authorization documents needed to be provided, including the copyright certificate, the copyright certificate of the music work, the singer's performance authorization letter, etc. At the same time, they also needed to provide identification documents such as ID cards, business license, etc. If the singer agrees to the authorization, the copyright of the song and lyrics of the musical work can be authorized to the singer. The singer can perform, release albums, and other activities. If the singer did not agree to the authorization, they would have to retain the copyright and could ask the singer to pay the copyright fee. In the process of authorization, he also needed to consider some legal details and consult professional lawyers or relevant departments for advice on dispute resolution.
