I paid $7 for this a year ago on my iPod Touch. I just paid $7 again. It is worth it for radio Junkies!
I also have Radio Time which is half the price and should do it for most people. But Wunder Radio has even more stations and servies. The app UI is beautiful! Looks great!
I will say it is Version 1.0 and the Dev wants feedback for improvement. I have experienced a couple FC and some slow/delayed streaming. But overall, so happy this is here! ESPN and this were the two most anticipated apps for me! (Now we just need a CNN app). Both are 1.0 and need improvements, no doubt, but its a great start!
