One of the greatest singer-songwriters of her generation, Parton’s greatest hits are some of the most influential tracks in the entire genre. Her illustrious track list includes classics ‘Jolene,’ ‘I Will Always Love You,’ and several other hits which would grant Parton global icon-status. She has transcended the music industry, and has since opened her own theme park (Dollywood), written a musical, and starred in several television programs.
