One more subjective list against which to check your own library. This list was compiled by the editorial staff of Country Weekly and was published in their 10th anniversary issue. I should note that they only ranked albums released during their publication run, which began in 1994. The cover date of the issue in which the list appeared was March 16, 2004.
1. Fly, Dixie Chicks 2. Double Live, Garth Brooks 3. Drive, Alan Jackson 4. The Woman in Me, Shania Twain 5. Not a Moment Too Soon, Tim McGraw 6. O Brother, Where Art Thou? Soundtrack 7. Blue Clear Sky, George Strait 8. Breathe, Faith Hill 9. American Recordings, Johnny Cash 10. How Do You Like Me Now?! Toby Keith 11. Blue, LeAnn Rimes 12. Red Dirt Road, Brooks & Dunn 13. New Favorite, Alison Kraus + Union Station 14. Did I Shave My Legs for This? Deana Carter 15. The Key, Vince Gill 16. Wide Open Spaces, Dixie Chicks 17. Come on Over, Shania Twain 18. No Shoes, No Shirt, No Problems, Kenny Chesney 19. Unleashed, Toby Keith 20. Nothin' but the Taillights, Clint Black
The only one I don't have is Vince Gill's The Key. I've got the rest of the list if anyone wants to see it and can't find it online.
