Awesome but not working

My friend had this and showed it to me about a week ago. It was awesome so I ended up getting it, but much later. By the time I bought the app it had broken. It has no sound. No point in a music app that has no sound. I hope this is fixed soon. I will give this 5 stars anyway because I know it will be fixed and once it is, it is a great app
