Superstar artists like Eminem, U2, Justin Bieber, Lady Gaga, Bob Dylan, Bruce Springsteen, Madonna and more have contributed tracks to “Songs for Japan” for the benefit of that struggling nation.

Two CDs worth of tunes – 38 total -- have been compiled and are now up on iTunes to be bought as a bundle for $9.99.  All artists, songwriters, publishers and other entities involved have waived their royalties. A double-disc set will be available in early April.

Other artists to contribute include Katy Perry, Black Eyed Peas, Keith Urban, John Lennon (well, his estate), Pink and Nicki Minaj.

None of the songs on the set are previously unreleased, but the price may entice those who wish to give to charity and appreciate the bundle at a small price than would be paid for the songs individually. One-hundred percent of the proceeds will go to the Japanese Red Cross, whose efforts have aided relief for the earthquake and tsunami-stricken country.
