I listen to a lot of "country" but you won't hear it on any FM station. Bluegrass certainly is a type of country music that had it's beginnings in old time mountain music. Original Bluegrass vocals had an antique quality that most modern BG singers can't imitate. Ralph Stanley claims his style of "mountain" music came before bluegrass and you have to be "borned" with that type of voice..........
If I've done the arithmetics correctly, as of today (September 6, 2011), the sum of all percentage figures yields 316.33 % !
(36.68+14.9+12.32+46.7+4.87+21.2+5.16+76.22+8.88+39.26+22.06+8.31+19.77 = 316.33)
