Query: Best Grammy pick ever -- EVERYONE should own this CD.

I can't add much to what everyone has said, I'll just recommend my favorite tracks: "Po' Lazarus", "Big Rock Candy Mountain", "Hard Time Killing Floor Blues", "Down to the River to Pray", "In the Jailhouse Now".The amazing thing about this album is that it achieved its (extremely well-deserved) critical and popular success without any radio airplay! It doesn't fit the pigeonholed categories (or "formats") whose dominance has ruined music radio, and demonstrates what a terrible shame and a scandal that situation is.Bob Dylan made a great folk/country album last year, and that the "O Brother" soundtrack is even better tells you all you need to know. It's so good I'm going to get the movie too.
