Is it possible for me to make a custom dimension have custom music?

   I really want to implement custom music into my mod, I think it might spice it up a bit, but I'm not very sure how I should. I am also not to much of a coder, Id look it up, but I'm not very sure what to look up so I thought going to the source might be a good Idea, and as a bonus question, can I make a custom working disc?
