Anthems or ambiance, these are the tones that rattle your bones.
I'd like to recommend the music artist Erutan (aka katethegreat19). Her real name is Kate Covington and she plays violin and sings, with styles ranging from medieval and Celtic, to covers of songs from movies, video games, anime, and more. In particular, I'd like to point you Halloweenies to these three tracks which I know a lot of you will appreciate:

Transylvanian Lullaby:

Come Little Children (from Hocus Pocus):

Sally's Song (from The Nightmare Before Christmas):

You can find her music on iTunes, Amazon, YouTube or her official website.

In fact, you can download all 3 of the songs from the above videos for free!
