Country Ready for Some Country

Country music lassoed the top three spots on the Billboard album charts this week in a first for the genre. "American Idol" winner Carrie Underwood claimed number one with her sophomore album "Carnival Ride," the amazing match-up of Led Zep main man Robert Plant and newgrass sweetheart Alison Krauss clocked in at number two and hat act Gary Allan rounded out the top trio.

While the Plant/Krauss collab isn't technically just country, c&w is definitely in the mix on "Raising Sand," which is every bit as good as you've heard it is.

Other notable, non-country debuts include the first solo set from System of a Down leader Serj Tankian at number four and rockers Coheed & Cambria's latest "No World for Tomorrow" at number 6.
