Pop musicians set to release compilation album to raise money for Japanese relief effort

  Justin Bieber, Rihanna and Nicki Minaj are just a few of the many stars that are set to be involved in a new charity compilation album. The idea behind the album is to raise funds for Japan, following the devastating natural disasters earlier this month.

  Executives at Universal Music are releasing a digital record later this week (ends27Mar11), 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 rumoured to be on the playlist include U2, Lady Gaga and Bon Jovi.
