Excitement for non-American iOS users yesterday, as Apple’s iTunes Radio started popping up on some devices in the UK and Canada. 9 to 5 Mac rounds up some of the joyful tweets, as people fired up their iPhone’s Music app to find iTunes Radio ready to go. Unfortunately for them, this seems to have been a mistake rather than the start of an official rollout, even though recent speculation suggests that both countries will be among the first markets outside the US to get Apple’s personal radio service. The article notes that the service has stopped working for those early users. While iTunes Radio attracted 11m users in its first few days in the US, the service’s big potential is rapid global expansion – something rivals like Pandora have never managed. With Apple’s Eddy Cue publicly targeting 100+ countries for iTunes Radio in the mid-future, we sense the UK and Canada won’t have long to wait.
