Minecraft "music" from marketplace wont download.

I dont know if its a bug, but when i try to download music from the marketplace, it would not continue download and stays at 0,00MB. When i restart minecraft, i didn't open marketplace and suddenly pop up "Download started: music" but it won't download still. When i check on it, it was 0,00MB out of 0,00MB. And if it's a bug, please fix it. (This only happens when im in my microsoft account)
