Apple is being challenged once again to open up its DRM by consumer groups in Europe. This time, Germany and France have joined the slowly-growing number of countries who are asking Apple to allow the protected songs purchased from the iTunes Store to be played on other music players besides the iPod. Norwegian Consumer Ombudsman Bjoern Erik Thon told the Associated Press that France's consumer lobby group, UFC-Que Choisir, and Germany's Verbraucherzentrale are now part of the European effort to push Apple into an open DRM system, with more countries considering joining the group.

By now, everyone who owns a digital music player of any sort is painfully aware that buying music from a particular online store locks them into that platform. Apple, the current market leader in both online music and digital music player sales, has been particularly stubborn about allowing its protected AAC files to be played on anything but iPods.

However, the company has been under some fire over the last year due to those restrictions, first with France and then Denmark looking to open up restrictive DRM schemes (including, but not limited to iTunes). Neither of those forced Apple to open up their FairPlay DRM, but last June, Norway ruled that the iTunes-iPod tie-in was unreasonable. Norway's Consumer Ombudsman gave Apple a deadline of June 21, 2006 to come up with a solution, but the deadline then got pushed back to August 1, 2006. Norwegian consumer groups were unimpressed by Apple's response.

Norway has now given Apple a new deadline of September of this year to change its policies, and the pressure on Apple will likely grow in the months leading up to the deadline. "This is important because Germany and France are European giants. Germany, in particular, is a big market for digital music," Thon said to the AP. Who will be next to join the group and how will Apple respond to the growing pressure?
