Add rewind to radio listening, just like for podcast. My defunct iPod Nano 6th gen did this and I loved it.
I listen to NPR a lot while doing other things, and quite often I want to go back, because I missed something, like what country they're talking about. The iPod Nano 6th Gen. had an FM radio with a 30-sec back button. I haven't been able to replicate that on my phone or other apps, including the NPR app. Please consider adding this feature. And thanks for a great app and your constant efforts to improve it.
