Minecraft PE Jukebox and Music Discs not Working? - 1

I just installed the most recent update as of August 3rd. I don't play frequently, yet decided to give the game a go regardless, given the update. I was surprised to learn that jukeboxes and music discs were added to the game. In survival after having a skeleton kill a creeper, I got a music disc. After placing it in a jukebox, all that I saw was a few colorful notes emerging from the thing. I waited and even tried again a few times. No music. Is this a bug/glitch of sorts? I was looking forward to in game music potentially making Minecraft more enjoyable to play.

Added (1). Well, the update is beta. Should I just stop playing and wait for the official update?

Yes
