by Brian Mansfield Diffie's second album has all the cliches of country music, and all the good stuff too. If "Ain't That Bad Enough" is a run-of-the-mill song, Diffie rescues it by tearing the melody loose from its mooring. He's also willing to push the line: of all Diffie's country heroes -- and you'll be able to name them after one listen -- maybe only Merle Haggard would rock out as hard as Diffie does on the title track.
