Johnny Cash helped lay out the foundation for classic country. Though this new country crap is just that, crap.
Rock, metal, darkwave, EBM, Industrial, goth, Emo (just a couple of the bands, hate the look), Johnny Cash (he is a genre all by himself), new wave, classical and many more. Not country.
Not sure if I mentioned symphonic metal, but who can't love Epica and Nightwish? Or After Forever for that matter.
