Songs For Japan, a compilation album, has sold over 500,000 copies, generating approximately $5 million in revenue to benefit the victims of the tsunami and earthquake that devastated Japan in March.

A press release indicates that the $5 million was given to The Japanese Red Cross Society.

The artists involved in the project, including Eminem, Cee-Lo, Rihanna, Nicki Minaj, the Red Hot Chili Peppers, David Guetta, The Black Eyed Peas, Elton John and many more, waived their royalties and proceeds for the project.

Among the songs included on the project were “Love the Way You Lie” by Eminem and Rihanna, “It’s OK” by Cee-Lo, “Save Me” by Nicki Minaj, and “By Your Side” by Sade.
