Minecraft music pack stuck at "importing content"

Dear devs,

Hello! I am a new player of Minecraft pocket edition and so far, the experience is really great but I have this problem with the music pack frim the market place. I can successfully download the Minecraft music pack yet when it goes to step 2 which is importing the content, the game starts to lag and goes back to either the marketplace or the title screen. When I go back to the marketplace, the music pack isn't downloaded and I need to repeat the progress only to experience the same thing that happened earlier.

 

I hope these reaches your attention and thank you so much for the response from your end!

Thank you!
