I had the same issue before. The song just couldn't be recognized and played, then I tried to use a video repair tool called Joyoshare VidiKit to "repair" it. It worked but I don't know how. But it's a relief that such an issue doesn't happen a lot. I love Pandora. ❤️

There is a big missing piece of the track just over halfway through. Every time it happens, I think it's an internet connection issue, but it's the same point in this song every single time. Bad transfer.
