MySpace, the popular online social network owned by Rupert Murdoch’s News Corp., could develop a digital music player in the future, pitting it against Apple’s hot-selling iPod. However, there are no immediate plans to make or sell such a device, MySpace cofounder and chief executive Chris DeWolfe said at the Web 2.0 Summit in San Francisco on Thursday. “It’s possible” that MySpace, which recently launched a music joint venture with major music labels, could eventually build a device for listening to music, DeWolfe said.
