This song by Bobby McFerrin won Song of the Year and Record of the Year at the 1989 Grammy Awards. It is a wonderful antidote for worry, and a huge pick-me-up when life sometimes gets us down. It always makes me smile. I posted it in 2018 as released by Bob Marley but apparently that is incorrect. Relax and enjoy the experience (again).
I also like the newer song “Happy.”
