U2, Coldplay and The Killers have all recorded songs for a new weekly music service which will benefit HIV-infected people in Africa.

Each issue of RED(WIRE), which will cost $5, includes an exclusive song from a major artist, as well as a musician the charity hopes to promote.

The service will launch on World Aids Day (December 1st) with The Killers' Christmas collaboration with Sir Elton John and Pet Shop Boys Neil Tennant, entitled 'Joseph, Better You Than Me'.

A song by U2, which was recorded last Wednesday, will feature as part of a later issue.

In addition to MP3 tracks, which can be download automatically onto iTunes, users will receive a multimedia piece such as video or photography.
