According to MTV News:

On Monday, we learned the names of some of the stars set to appear on Songs For Japan,
a compilation album to benefit the ongoing disaster relief efforts in
the earthquake- and tsunami-ravaged nation. And on Friday (March 25),
not only was the full roster of artists and songs revealed, but the
album was made available for purchase on iTunes.

Lady Gaga, Eminem, Beyoncé, Madonna, the Kings of Leon and Katy
Perry joined a list of already-announced artists like Justin Bieber,
Nicki Minaj and Rihanna on the album, which is available worldwide on
the iTunes Store for $9.99. Proceeds from the sale of Songs for Japan will benefit the Japanese Red Cross Society.

All in all, 38 artists lent songs to the album, including
legends like Bob Dylan, U2, Bruce Springsteen and the late John Lennon;
country acts like Keith Urban and Lady Antebellum; rock artists like
the Foo Fighters, R.E.M. and Bon Jovi; pop icons like Madonna and Pink;
and top hitmakers like Bruno Mars and David Guetta.

All acts appearing on Songs for Japan — and their labels
and music publishers — have waived their royalties and proceeds from
the worldwide sales of the album to insure the Japanese Red Cross
Society receives as much support as possible. The JRCS will use funds
from the album to support its ongoing relief efforts and for eventual
recovery assistance to the areas hardest hit by the earthquake and
subsequent tsunamis. iTunes will also donate its proceeds from the
album’s worldwide sales to the benefit of the JRCS.
