You can listen to new material donated by the acts now

Artists including Jay-Z, The Killers, U2, Coldplay and Kylie Minogue have donated tracks to a new charity download service.

Redwire is an online magazine that supports people infected with HIV in Africa.

Subscribers are asked to pay £4 per month in return for four exclusive tracks, with half the proceeds going to Bono‘s Red charity.

A number of exclusive songs featured on the service are being streamed on MSN now.

Among the tracks is a new Jay-Z song featuring Santogold (‘Brooklyn Go Hard’), U2 covering Greg Lake‘s ‘I Believe In Father Christmas’ and a collaboration between Coldplay and Kylie Minogue entitled ‘Lhuna’.

The Killers‘ duet with Elton John, ‘Joseph, Better You Than Me’, is available to listen to as part of the (Red)wire service.
