In the tradition of hits like Band-Aid's "Do They Know It's Christmas?," USA for Africa's "We Are the World," and Artists for Haiti's reboot "We Are the World 25: For Haiti" comes a new star-packed chart hit recorded and released for a vital cause.

All-star single "Love Song to the Earth," billed as by Paul McCartney & Various Artists, debuts on Billboard's Pop Digital Songs chart (dated Sept. 26) at No. 36 with 11,000 first-week downloads sold in the week ending Sept. 10, according to Nielsen Music. Proceeds from the song's sales go toward the Friends of the Earth and the U.N. Foundation in their efforts to inspire further international action on issues related to global climate change.

Among the song's 16 credited artists are Natasha Bedingfield and Sean Paul (two of the ballad's writers), Jon Bon Jovi, Sheryl Crow, Fergie, Moby, Colbie Caillat, Goo Goo Dolls' John Rzeznik, Leona Lewis, Nicole Scherzinger, Krewella, Kelsea Ballerini and Victoria Justice.

"Love Song to the Earth" will receive key exposure Thursday, Sept. 24 when Bedingfield, Paul, Justice and others will perform it at the National Mall in Washington, D.C. as part of the Rally for Moral Action on Climate Justice.
