Showtime Promo music

[song_freak]

Hey, everyone. I can't tell you how great this site is. Every time I get a song stuck in my head that I don't know, you all have the answers. I just saw a Showtime promo today for their original series. It was a woman singing a kind of sad song over a montage of all Showtime's original shows. The music sort of reminds me of the "O Brother Where Art Thou?" soundtrack. Having a tough time remembering lyrics. I checked the Showtime site and coudn't come up with anything. Any help would be greatly appreciated. Thanks.

For anyone interested, the song is "Slumber My Darling" as sung by Alison Kraus. Apparently it was used on other shows too, like Alias.
