The governments of European nations are becoming quite the thorn in the side of digital music powerhouse Apple.

With the British Phonographic Institute calling for Apple to makes its digital rights management (DRM) work with other music players and France considering legislation that would require it to do so, Norway chimed in today, saying the iTunes user agreement breaks Norwegian law.

The Norwegian Consumer Ombudsman said today that the iTunes user agreement should not be regulated by English law, as it currently is, but rather should be regulated by Norwegian law. Because it is not, the ombudsman ruled, the agreement violates Norwegian law and Apple has two weeks to fix the agreement to comply.

Apple must respond by June 21 or face fines.

The matter first arose in January, when Norway's Consumer Council asked the ombudsman to look into whether iTunes violated the country's consumer protection law because its iPod players do not work with rival digital music services like Napster and Rhapsody, and because songs downloaded from iTunes won't play on rival players like those from SanDisk and Creative.
