Beyoncé's World Humanitarian Day song about "Our Dreams"

The singer talks about her track 'I Was Here' and says it is about leaving a positive influence on the world.

Beyoncé has said she wants her song for World Humanitarian Day to have a positive influence on the world.

The track, 'I Was Here', features on the singer's last album '4' and Beyoncé performed it during an event at the United Nations General Assembly Hall in New York earlier this month.

The song will be released on 19th August with proceeds going towards World Humanitarian Day.

Speaking to US host Anderson Cooper on his show 360, Bey said: "It says, 'I want to leave my footprints in the sands of time' and it basically is all of our dreams, I think.

"And that's leaving our mark on the world. I feel like we all want to know that our life meant something."

 Beyoncé was joined during the interview by under-secretary-general and emergency relief coordinator Valerie Amos.
