In a move that could shake up the growing field of Internet radio, Apple plans to develop a service that would compete with Pandora Media by sending streams of music customized to users’ tastes, three people briefed on the plans said late Thursday.
 
Apple, which has already dominated the field of digital music with its iTunes store, is in the early stages of negotiating with the major record labels for the service, and the full scope of its plans were not clear, according to these people, who asked not to be identified because the negotiations are private.
