Another Day of Sun is a song about Los Angeles in the US, a city of chances, beauty and disappointment (失望). It is the opening song of the musical film La La Land (《爱乐之城》). The movie starts in a traffic jam (交通拥堵) ‑ cars are lining up, with horns honking (鸣喇叭). Then the music comes in. To shoot this opening scene (场景), many actors danced in heavy traffic, and the road was closed for a weekend. This song is fast and joyful, but it is also a bit sad. It’s about dreams that are not realized.
