Who’s the target audience for the new iTunes Radio? Me. My family and I have a bunch of Apple devices, a WiFi network built around an Apple Time Machine, and not enough technological savvy (or time) to figure out workarounds. I signed up for Spotify a while ago, and like it. But I can’t figure out how to get it to play on the multiple speakers hooked up to my WiFi network, so I imagine that when Apple’s alternative is rolled out this fall I’ll immediately start using it instead. I might even pay extra for the ad-free version.
