Artists are rebelling against major labels Sony BMG and EMI.
They are angry at copy protection the labels are applying to new releases - particularly because the technology doesn't work on Macs and forbids music fans from burning their legally-owned music in a format suitable for iPods. iPods account for 80 per cent of digital-music players sold.
In reaction to this, acts are telling their fans how to undermine the system used.
Reuters reports that bands whose labels have released such CDs are enduring torrents of complaint from frustrated iPod-owning music fans, who didn't realise the protection existed when they bought their records.
"One solution artists offer to iPod users is to rip the CD into a Windows Media file, burn the tracks onto a blank CD (without copy protection) and then rip that CD back into iTunes," the report states.
Jason Brown, president of Philadelphonic, a management company that represents Tristan Prettyman told Reuters: "Copy control as it stands right now is in its 1.0 phase. It was rushed through and into a system that wasn't prepared for it."
Sony BMG even offers angry music lovers a link to pages on its website which teach them how to get around the technology the label has itself applied.
The company wants music fans to pester Apple into licensing its digital rights management technologies.
"Anything that smacks of corporatism, people don't like," one band manager told Reuters. "You are upsetting the fan that went out and purchased the record."
