First off though can someone point me towards a point in the code that uses {value 16}?
As I mentioned previously, I do not think it is used in the game. There is also a {value 32} that I know is not. I would try doing it the same way as {value 8}, except that you now need to take care of two bytes instead of one.
how is Magus's castle, or black omen keep their song's continuous even when you switch screens.
There are a few different ways of doing this. Probably the best, and the way I think I did it in the teaser, is to set all of the Locations to no default music (value FF). It will play no music on its own, leaving whatever music was previously playing going.
