RealNetworks says it has created technology that allows songs purchased through its online music services to be played on Apple Computer's popular iPod player, just a few months after complaining that Apple was rebuffing attempts to form an alliance.

In an interview Friday, RealNetworks chief executive Rob Glaser said he did not know how Apple would react to the new technology. Apple, based in Cupertino, Calif., did not return numerous phone calls from The Associated Press seeking comment.
