There’s a great article at PopMatter by Andrew Gilstrap providing steps to win friends and influence their aversion to twang. Step one is:
Realize Your Limitations
Straight off, admit to yourself that you probably won’t get anyone to replace their Celine Dion or Sting CDs with Hank Williams or Jason & the Scorchers. If they’re that far gone, there’s really no helping them anyway. So be realistic, and merely hope that your friends will begin accepting twang with the same tolerance with which they might greet their jovial but slightly off-kilter uncle at Thanksgiving.
