Universal Music Group has announced that it will be releasing a digital-only compilation album featuring some of the label's biggest stars, in an attempt to raise funds for tsunami-stricken Japan.

Rihanna, Nicki Minaj, Justin Bieber, Lady Gaga, U2 and Bon Jovi are all expected to appear on the album, waiving their royalties so that the entire proceeds will go towards Red Cross Japan. "We are doing it only digitally because it is faster, and this will be a worldwide release. The plan is to have it available later this week," a spokesperson for Universal explained. The as-yet-unfinished compilation will likely feature several other artists from the label.

Lady Gaga lost no time in joining the relief effort, tweeting that she had designed a special prayer bracelet on Friday, March 11, just hours after the earthquake shook Japan. In two days, Gaga and her loyal fans had raised over $250,000.

Singer Ne-Yo is also contributing to the country's aid by performing at several charity concerts in Japan (sans backup dancers), one of which takes place today, and another on Thursday, March 24.
