What better way to celebrate Alan Jackson's 20 years in the music business, and his whopping 34 No. 1 hits, than with a career retrospective? Beloved songs such as "Where Were You (When the World Stopped Turning)," "Here in the Real World" and "Remember When" sit alongside upbeat gems like "Who's Cheatin' Who," "Little Bitty" and "It's Five O'Clock Somewhere." Three new songs are included on this masterpiece: his hit with the Zac Brown Band, "As She's Walking Away, " plus "Look at Me" and "Ring of Fire," an updated, swinging version of the Cash classic. Perfection.
