What is your witch's theme song?

Not the aesthetic kind. Nine songs that are older, stranger, or more literal than most people know. A Welsh goddess. A Child ballad about holding on. A dirge sung over a body all night. A spiritual that was also an instruction.

Three ways in. Answer ten questions and let a song find you. Name all nine from three escalating clues. Or go straight to the deep cuts and see how much of the history you actually hold.
