Most Haunting Fleetwood Mac Song

[Conga]

So many Nicks songs from the first three album she was involved with had those mystical, I find those haunting because of her smoky voice (in it's prime in the 70s) and ambitious songwriting; Rhiannon, Gold Dust Woman, Silver Springs (haunting in that she sounds like she's going to hunt down and kill ya, man!), Sisters of the Moon, and more than any Sara

Future Games
I'm So Afraid
Over and Over is just haunting in it's beauty, production, the swelling of the background vocals, oh man!
Brown Eyes
Welcome to the Room Sara - I don't care what the others say
Woman of a Thousand Years

most redundant, but still thought I'd share my choices
