Cline was best known for her rich tone and emotionally expressive bold contralto voice , which, along with her role as a mover and shaker in the country music industry, has been cited and praised as an inspiration by many vocalists of various music genres.
Posthumously, millions of her albums have been sold over the past 45 years and she has been given numerous awards, which has given her an iconic status similar to that of music legends Johnny Cash and Elvis Presley. Only ten years after her death, she became the first female solo artist inducted to the Country Music Hall of Fame. In 2001, she was voted by artists and members of the Country Music industry as #1 on CMT's television special of the 40 Greatest Women of Country Music of all time, and in 1999 she was voted #11 on VH1's special The 100 Greatest Women in Rock and Roll of all time by members and artists of the rock industry.
