How to I make a good Music player?

Hi, I can't make music play in one place and not all over the map I only want it to play in one room so you cant hear it outside the room, also I want it to have a playlist so its not the same song over and over again! (sort of like pizza place, so when you walk in "the dump" it plays a song)

There's two ways to go about this. The first one is having a trigger brick that when you walk into a room it stops the current song, and plays the new one. Or you could have a part in the game with a Sound instance as a child, but that would not sound as clear.
