The trio songs, "Light the Passion, Share the Dream" "I am A star" and "Smile Beijing", which jumped out from nearly 80,000 contested songs, were finally released at the Fourth Olympic Songs Contest on Wednesday evening.

The "Light the Passion, Share the Dream" for the Olympic torch relay, was composed by Chris Baobida and written by Huang Xiaomao, who compared the Olympic flame to the eternal starlight, symbolizing that people, led by the light, will be united to realize the dream of friendship, hope and harmony.

One of the theme songs for the volunteers -- I am A Star -- was created by famous Hong Kong music men Emil Chau and Lam Jik. Lam regards in his lyrics the volunteers to the bow and the wind, which are source of the power and success.

"It is the volunteers who are the real Olympic stars," Chau said.

Another volunteer theme song "Smile Beijing" was created by Chen Ying, who works for the Beijing Olympic Volunteers Committee. Chen expressed his hope that everyone would remember the sentence "Volunteers' smile is the best calling card for Beijing."

This song was also carried to the space by China's first lunar probe satellite Chang'e-1, which sent back the signal of the song on December 4, 2007.
