I know this issue has been reported on before and causes the music to not play in the game. I have found that this can be fixed by downloading the Vanilla Music file off of the internet and I can confirm after extracting the 1.19.81 apk that the music files are missing from the game.
Some ideas I have to fix this issue:
Re-add Vanilla Music to the marketplace or add into the game files

Update: I cleared the cache/data of google play services and reinstalled the app. Seems to be working fine now and it could have been an error as I haven't reinstalled the game since around October. I usually use a file explorer to move resource packs and could have deleted vanilla music by accident.
Could you please specify where you installed the game from?
