Kacey Musgraves dropped a reimagined version of the song
on April 22, 2020 to celebrate the 50th Earth Day. The singer added some '70s bongos and acoustic guitar as a nod to when Earth Day started in 1970.
The release of "Oh, What a World 2.0" coincided with the COVID-19 pandemic, so the singer dedicated the song to frontline workers dedicated to stopping the spread of coronavirus. "There's a lot to feel downhearted about this Earth Day," Musgraves reflected. "In the face of a pandemic that has brought cities to their knees, a song can feel small. A melody can seem insignificant. This is a global moment of acknowledgment and respect for the power of nature and for so many of us - extreme challenges and sadness."
