Use debugging and improve your question with the error and the code that is creating conflict.

First of all, which audio library are you using? Which musicTagReader library are you using? And we cannot tell you how to optimize your code if we have not seen it yet.

As NotPolliticallyCorrect said, use the debugger to know which lines of code are creating conflict and what is the error thrown. Then you should post the question saying what is the problem occurring in your project.
