The Dutch consumers association Consumentenbond has become the latest national agency in Europe to pressure Apple to change the restrictions on songs bought from its iTunes website. Spokesman Ewald van Kouwen has confirmed that his group has filed a formal complaint with the Dutch competition authority NMa asking for an investigation into what he called illegal practises.

Songs downloaded from iTunes cannot be played on any other players than an iPod. ‘When you buy a music CD, it doesn’t only play on players made by Panasonic,’ he said. Similar complaints have been made by consumers groups in Germany, France and Scandinavia.
