She's a multi-platinum, 4 time Grammy winner, with a song that's included in a few best songs of all time lists, people have been covering "Fast Car" for the last 3 decades, and one of those covers was big hit in 2015

Maybe it's not about the coin but about the principle, she wrote and arranged that particular song herself, now it's out there attached to this tacky ass rapper is probably what has her in fumes
It's like when Prince gets a bit

when people ask to cover or sample his music
