With a legend like Hank, than man who largely dragged country music into the modern age, the question is how do you pick just 40 of his songs? There were the immediately obvious biggies like "Hey Good Lookin'," "Jambalaya," and "Move It On Over," but almost everything was a gem in one way or another. Whether this collection is the greatest hits or not will depend on the listener, but for anyone with even the slightest curiosity about country music, it's essential listening. Hank was a landmark of the genre, and to hear him is to understand how country could change from rural to urban. Essential listening for everyone. --Chris Nickson
