To reduce sound transmission you need one or more air spaces, this reduces the path that sound can travel through.
First option is two or three solid core doors where you create an air gap between each. I don't know your room or construction of your space so I can't elaborate on how and where to hang them.
I had a hollow core door on the utility closet housing our central AC unit. I replaced it with a solid core plus a fiberglass panel on the back and it reduced the sound enormously.
Upgrading the second door to solid core, the hall way door between the utility closet and my listening room removed all noise competing with the music.
Sound works the other way around too. Stopping it from going through to the bedroom is the same approach. Gaskets may be required if you have much space under the door and unless the walls are filled with fiberglass sheets like I've done in my room, the door may no longer be the transmission path after upgrade.
