How do I make music that overrides enemy music?

I think the confusion is because sounds work the opposite.

Sounds with a higher value will be canceled earlier as sound channels run out, so for example monster sounds you want to be 0, to make sure that they always play, but sounds for physics can be 10 as it is not important if it skips the impact sounds every now and then.

For music, 0 is used for ambient music tracks, as that is most likely what you like to use for base music. Then playing a piece of event music as priority 10 will make sure it plays, and when it is over it stops and the priority 0 music will resume (ambient track).
