iRadio disappeared while playing. I could not restore with shut down

Was solved by force-closing, then reopening, the Music app.

To force-close the Music app, first double-click the home button to display your recently used apps. Then, flick up on the app preview to force-close it. When clicking back on the music app it was there.

Hope that helps!

I found that when i connected to my iMac, it required an update, version 11.1, to iTunes. After that update, it told me to transfer my purchases from my iPhone to iTunes. Then it said i needed to update my iPhone software to iOS7, even though i had already done so. I did it anyway and after snyching, everything works beautiful and iRadio is back. Hope this helps.
