Sony BMG is releasing iPod-incompatible copy-protected CDs.

The company has elected to utilize console-contender Microsoft's Windows Media software in order to ensure its releases against piracy, angering some users.

Recent releases from the company incorporating such protection come from the Foo Fighters and Dave Matthews Band, according to Reuters.

A sizeable majority of music fans are incensed.

"About one-third of the 252 customer reviews of the Foo Fighter CD this week on Amazon, which prominently displays the fact the album is a copy-protected CD, complained about the copy protection," Reuters writes.

In a strange twist, Sony itself reveals how users can bypass the rights management it has applied to its music releases on optical discs.

Some commentators have pointed out that CDs with copy protection are not actually CDs, as they don't conform to CD standards.

Sony said: "Users can get the music onto iPods by transferring files to a PC, burning them to a CD, ripping those and transferring them into iTunes." Effectively, this method can be used by any pirate wanting to release the tracks through any file-sharing service, rendering the exercise a pointless and expensive move by the company.

Reuters confirms label executives to be "in talks" with Apple to make protected CDs iPod-compatible. Sony BMG has also released versions of the album through iTunes.

Apple hasn't yet licensed its own digital rights management system, FairPlay, to labels.

"It's up to Apple to flip the switch," said one record label executive.
