Melody, "Best for You" and "Please Listen to My Friends" have a high degree of similarity, and are also very similar to the songs of singers Ka Jie and Bieber, and the climax part is also very similar to the theme song of "Slimming Men and Women". But from the music itself, it sounds good. Judging from the development trend of today's music scene, plagiarism is difficult to define. There are many classic songs with similar melodies, which only shows people's unanimous recognition of beautiful things. For a beautiful thing, since it is a beautiful thing, the first person who created it can't stop others from pursuing it, and intellectual property rights can't be applied to everything. As far as plagiarism itself is concerned, it is difficult to know whether it is original or imitation. Imitation music can be listened to, of course, and it will be nice, but the melody is not innovative enough. From a professional point of view, good music is not only a good melody, but also needs to enrich the theme of harmony and musical motivation in order to achieve more exciting results.

Good-looking skin is the same, and so is music. There are only a few beautiful melodies. Listen to them more, there will be many similarities. Melody makes people appreciate and taste well, makes listeners feel happy and comfortable, and achieves the original intention of being a musician. In fact, it is difficult to draw a certain line, or to identify music plagiarism. As far as music itself is concerned, as long as it is good, this song is a success. People who listen to songs listen more if they like it, and don't listen if they don't like it.

We don't have to waste time obsessing about the originality of Nana Ou-yang's songs. When we want to listen, we feel very comfortable, like it very much and listen well. That's enough. When we listen to music, it's not just melody. I think it is more important that Nana Ou-yang's personal charm attracts us, including Nana Ou-yang's sweet voice, outstanding temperament and talent, gentle personality and so on.
