If someone recommends a song to me, they say that the arrangement of the song is very good, the harmony is full, the chord progression is interesting, the key has been changed several times, and the violin solo part is backed by strings. . . . . I probably couldn't be bothered to listen to him and lost interest in the songs. . If you don’t have professional knowledge, my suggestion is to tell stories. Tell what you know about the story behind the song, what the lyrics mean, and how it makes you feel. This is enough. If you want to make some subjective evaluation of the song, remember to add "I personally think..." at the front. If you must appear objective and professional, then break it down into several elements.

1 For the composition and arrangement of songs, see How do people who have never studied music theory evaluate the arrangement of a song?

2 The method of evaluating song lyrics can be found in the evaluation of poetry learned from childhood to adulthood, which is nothing more than emotion, wording, and the degree of coordination with the melody.

3 The singer of the song. The evaluation method is simpler, Baidu.

4 If you want to be more professional, you can ask how to judge whether the mixing of a song is excellent?
