2014 came and went without much news for iTunes. There was no international expansion for iTunes Radio, and no word on Continuity for iTunes or media. There was, however, Apple's acquisition of Beats Music. I can only imagine it caused a bit of a scuffle in the company's media department, tossing out old plans and demanding new plans be made.
As such, I'd have been surprised if Apple wasn't working on a new, hybrid music service. But it's the how and the what they're going to do with it that's interesting to me.
