Music is not in because it doesn’t really add much in a sandbox, and it’s generally massive in file size. Adding a single track of bgm would more than double the file size, and nobody likes load times. You're welcome to listen to your own music library while playing.
At the end theres a spot where you can kill boss and he gets stuck on corner, use a long range sword and u can hit him but he cant hit you i did this on insane mode and won, too easy 3/5
There are two search fields already, in the Spawn menu as well as the Library.
