Anyone who is still clueless about what a great singer Ronnie Dunn is need only grab this second greatest-hits package from Brooks & Dunn, a 17-song compilation that skims the commercial high points from the duo's 1998-2004 period. Dunn, the quintessential balladeer, soars on honky-tonk laments and reminiscences like "Red Dirt Road" and "How Long Gone," and on full-throated romantic plaints like "That's What She Gets for Loving Me" and "It's Getting Better All the Time." His sidekick, the underrated guitarist, utility singer, and all-around dynamo Kix Brooks, also gets his moment to shine on a marvelous '60s-style, 18-wheeler ditty called "Independent Trucker," one of three new cuts included here. --Bob Allen
