A star-studded charity cover of REM's Everybody Hurts is available for download to raise money for Haiti earthquake victims.
Under the guidance of X Factor supremo Simon Cowell, some 21 acts united to record the single, including Leona Lewis, Susan Boyle and Kylie Minogue.
The moving ballad will hit the shops on Monday, with those behind it hoping it will top the charts and provide much-needed funds in the process.
Originally a hit in 1993, the song has been reworked with vocalists including X Factor winner Joe McElderry, Rod Stewart and JLS.
The recording also reunites Robbie Williams with his former Take That bandmates Gary Barlow and Mark Owen.
It was recorded in London and Los Angeles and got its first airplay on Tuesday.
REM are waiving royalty rights to the charity track, while the Government has said that there will be no VAT cut.
Proceeds will be split between the Disasters Emergency Committee and The Sun's Helping Haiti campaign.
Up to 200,000 people are believed to have died as a result of the 7.0 magnitude earthquake on January 12, with hundreds of thousands more left injured and homeless.
