The word "Sao Song" has an unusual meaning in pop music. Different from ordinary songs, it is more psychedelic and emotional, and often expresses a kind of meaningless publicity and helpless sadness. Sao songs are usually created by people with stories and feelings in the depths of their souls. They use music to vent and release their hearts and spread their feelings to the world.

The melody of Sao songs is usually simple but beautiful, neither melodramatic nor too indifferent. They combine pop, rock, folk, electronic and classical elements to produce a brand-new style. This style is very popular among young people because it makes people feel emotional. This kind of music style also reflects the spirit of young people's pursuit of freedom, independence and individuality in the new era.

The development of Sao song music is due to the change of pop music market and the demand of entertainment audience. People's pursuit of pop music is not only to hear music with interesting melody, but also to find a kind of soul singing in it. The emergence of Sao songs just meets this demand and opens up a new field in major music circles. It allows those who love music but have their own stories to express their feelings in a musical way, which has been welcomed by countless young people and become a contemporary music school.
