Yea, no probs keep them in
Just a suggestion for the readme: would be great if you put it in a "documentation" folder inside of your mod folder, according to this post

There are some neat features JSGME provides this way plus its granted to use the conventinal structure for SH reducing file clutter in the games root dir as best as possible.
If you dont mind I'll keep you updated for adds/alterations in my sound mod in the near future here within this thread.
Cheers
