Update: Peter Kafka, over at All Things Digital, backs up Reuters' claim with some additional detail. Unlike Amazon's approach with Cloud Player, Apple is actively seeking to license the music for its streaming service before launching. According to Kafka's sources, Apple has already secured deals with two of the big four labels and plans to launch "pretty soon." The deal would allow Apple to store a single master copy of a track on its servers and then share that track with multiple users. As Kafka describes the service, "The idea is that Apple will let users store songs they've purchased from its iTunes store, as well as others songs stored on their hard drives, and listen to them on multiple devices."
