Hi there !!
I've actually updated the license terms on the page to make things a bit more clear.
Having music anywhere in the project (even in separate files) goes against my principles and the updated terms, so I kindly ask you not to use the voice pack in this project. I truly appreciate your understanding.
However, in case you resolve this issue and use the pack appropriately, I'd be happy to check out how my voice sounds in the server through a short video or any way that suits you!
