Japan charity album

From Q1043.com:

Stars including Justin Bieber, Rihanna and Nicki Minaj are offering up their songs for a compilation album to raise funds for Japan following the devastating earthquake and tsunami earlier this month.

Executives at Universal Music are releasing a digital record later this week, with the profits going towards the Japanese Red Cross relief appeal.

A spokesperson for the label says, "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."

Other artists rumored to be on the playlist include U2, Lady Gaga and Bon Jovi.
