For bigger servers, it's common practice to have designated "DJs", which are able to manage music playback.
Using Groovy's permission system you can also create such a role. Below is a guide on how to do so.
1. Create the DJ role
This part is fairly easy. All you have to do is create a role to be designated as the DJ role. For convenience, this guide assumes you name your DJ role "DJ."
2. Grant permissions to the DJ role
The next step is to grant permissions to the DJ role. A conventional DJ role will give DJs access to all permissions.
So, use the allow-all command
/perms modify @DJ | allow | all
3. Remove the permissions from the everyone role
Next, you will have to remove permissions from the everyone role.
If you still want users to be able to do basic things like add songs to the queue and look at the queue, then you should only deny Manage Player and Manage Queue. The commands for that are
/perms modify @everyone | deny | manager player
/perms modify @everyone | deny | manager queue
If you don't want regular users to be able to do anything, then just do
/perms modify @everyone | deny | all
Removing the DJ role
If you want to remove the DJ role again, just run the following commands:
/perms modify @everyone | clear | all
/perms modify @DJ | clear | all
