EMI

EMI are currently the record label for Pink Floyd. However, there has been recent debates over loyalty issues from online sales of Pink Floyd's albums. According to the developer of The Dark Side of the Moon and other top-selling albums, its contract with EMI requires its music to be sold as an entire album, not the single tracks that EMI has permitted iTunes to distribute. Lawyers for Pink Floyd had argued that a clause in the contract "expressly prohibits the sale of albums in any configuration other than the original configuration". This, supposedly has lead to £10m in unpaid royalties to the band. This has lead to a legal battle between Pink Floyd and EMI, resulting in EMI being ordered to pay £40,000 in costs. The band were not present to hear the judgment at the High Court in London.  

Instances such as this have been reflected by bands such as AC/DC, whose albums are not available on itunes. For a brief period Radiohead did not allow their albums to be released on itunes for similar reasons, although the most recent, and popular example of this has been the Beatles, who have now released their entire catalogue to itunes, after a many years of negotiations.
