Dolly Parton has been awarded TWO Guinness World Records.
One is for the "Most Hits On a U.S. Hot Country Songs Chart by a Female Artist." She accomplished that by having a total of 107 hits. (So far.)
The other is the "Most Decades with a Top 20 Hit on the 'Billboard' Hot Country Songs Chart". That spans six consecutive decades . . . starting in 1967 with a song called "Something Fishy", to last year's version of "Jolene" with Pentatonix.
