Listen to David Guetta on iHeartRadio

Over the weekend, David Guetta premiered his music video for "One Voice" featuring Mikky Ekko (you may recognize him from Rihanna's hit "Stay").

Joined by Secretary-General Ban Ki-Moon at the United Nations in New York, Guetta debuted the new music video in support of the #TheWorldNeedsMore social media campaign.

The campaign is raising awareness and funds for World Humanitarian Day. By tweeting #TheWorldNeedsMore and/or #YourWord, each tweet raises $1 for Typhoon Haiyan victims in the Philippines.
