Mike, I have experienced this problem. I can't say when it started as I only tried the thread yesterday. Today, however although there is no visible youtube 'box' or video I can keep tapping and get the music on meatloaf bat out of hell and apache by the shadows. I haven't tried all the missing but it's certainly weird. This seems to be a result of upgrading to iOS 7 by apple. Essie xxxx
I had a problem with my laptop once when it had automat updates so I set it to an earlier restore point and voila ... links appeared again. I don't know much about i pads but I know that there will be some things not available to mobile users due to copyrights.
Thank you for trying to help with this problem. I have reset everything I could think of and now I seem to be able to get the videos on alphabetic artists again, but not all the time. Sometimes I can get a blank screen but if I hit it on the right spot, I get the music. Essie
