I need to delete the music section. How do?

The question is simple but do not know, can you help me?

Delete or disable.?!

Disable: Admin Dashboard -> Builders -> Nav Menu

find Music and allow niether Member or Non-Member to view/use

Ensure no use by NEVER allowing those MUSIC Membership Actions in the: Admin Dashboard -> Settings -> Membership Levels

select the Level to reveal the actions: Manage accordingly :)
