An issue I am having for MCPE on my iOS device is that the music pack from the marketplace will not download to my device.  The download will start properly and get through step one of two, but when step two begins it freezes and stops the download.  The pack is not added to my device and starting the download again results in the same thing happening.  I have downloaded other packs from the store without problem, but this one specifically will not download.  I have included a video as an example.
