— David Guetta can’t wait for you to hear his new song “One Voice” — for a couple of reasons.

The song is at the heart of a new partnership with the United Nations, and the 46-year-old French producer and DJ hopes it will inspire fans to donate money for humanitarian relief around the world, simply by tweeting. It also shows a brand new side of his musical personality.

“It’s a big turn for me,” Guetta said of the song that features singer Mikky Ekko. “I’ve never had songs that are like this kind of subject, so I’m really excited about this. It’s a big change lyrically, but also sonically. Just, you know, growing up, trying to do something bigger than myself.”

Guetta will project a video for “One Voice” on the side of the U.N. building in New York tonight with the help of Secretary-General Ban Ki-moon, helping raise awareness for the “The World Needs More ...” humanitarian aid campaign. Fans can trigger $1 donations by choosing a word to finish the sentence, “The world needs more ... ,” and tweeting #worldneedsmore# #yourword#.

Guetta is backing the word “love.” Other sponsors chose words like inclusion, education, dreams and empowerment. Fans also can donate $1 by sending a text. Details are available at the campaign’s website where the video unveiling also can be watched via livestream tonight.

The campaign launched in August on World Humanitarin Day and was spurred by the devastation caused in the Philippines by Typhoon Hyian. The money also will go to “other parts of the world like Syria, and everywhere people are suffering,” Guetta said.
