Billy Ray Cyrus -- Eat Your Achy Breaky Hearts Out, Suckas ... I'm On The Rap Charts!

Go ahead and laugh ... we all did the first time, too ... but the hip hop version of Billy Ray Cyrus' "Achy Breaky Heart" is a huge hit on urban radio -- even beating out Drake on Billboard's rap chart.

Billy Ray clearly feels urban vindication ...with a smug look of satisfaction as he waved the new Billboard chart from the window of his SUV.

"Achy Breaky 2" -- featuring Buck 22 and Billy Ray -- debuted at number 11 on the Hot Rap songs chart -- edging out Drake's "Worst Behavior" at #12..

BTW "Achy Breaky Heart" was a number 1 hit on the country charts for five weeks in 1992 ... the year Miley was born.
