When you're talking country, you'd better not be using "new country" and "best" in the same sentence. Everyone knows that the best country is the old stuff, and the fact that country-music record sales have rapidly slumped in recent years is a signal to Music Row that people have caught on.
Since there's no longer a reliable radio signal for picking up old country (unless you cover your body in tinfoil and point it in the direction of Austin), we recommend you try KUET-AM, the nostalgia station that broadcasts "timeless classics" out of Black Canyon City. KUET's broadcast day includes all the fundamentals of country, from back when country was cool -- Johnny Cash, Johnny Horton, Glen Campbell, B.J. Thomas, Marty Robbins and Patsy Cline. It's worth slogging through the Platters, Percy Faith and Barry Manilow just to hear the occasional Roger Miller or Bobby Bare hit.
When this old-pop-is-really-new-country controversy gets out, it'll turn country-music radio on its ear. In the meantime, you can trace where new country got its roots dyed with Olivia Newton-John, Barbara Mandrell, Kenny Rogers, Eddie Rabbitt and John Denver. Until Arizona gets a radio format that meets David Allan Coe's checklist for what makes a great country song, KUET is the best bet for hearing at least one song per hour about drinking, trucks, trains, prison or mama.
