The issue was added to comments of MCPE-18536, but I guess it was hidden behind something like music options showing while the music not being present in some devices.

Well, in Windows 10 edition, the music was there in 0.16.1 (and earlier versions) and it is gone in 0.16.2. So I'm creating this issue to specifically track the issue that was introduced in 0.16.2 for Windows 10 edition. I don't know if other variants are affected by this as well.
