iTunes Radio how to…

Where can I find iTunes Radio?

iOS 7 required. the iTunes Radio service is available only in US right now (as of 09/20/2013).

iTunes Radio can be found on Music app. look at the bottom of the screen with tabs. "Radio" is the left-most tab.

iTunes Radio is playing only clean songs. how can i turn on dirty versions?

start playing a station. open Now Playing view. at the top of the screen, there is "i" icon. tap that. toward the bottom of the opened screen, there is: Allow Explicit Tracks. turn it on.
