App rejected on 4.3 Design - spam

I have stuck with 4.3 policy for around 1 month. I don't understand Apple reviewer kept hitting me with 4.2 policy without further explain the problem.

I do refer to other app and copy some code from stack overflow, how do I know which part is causing the problem. My app provide better soothing sound quality and the UI is all different.

Thanks, kindly advise .....
