It’s over a decade old, but this USA for Africa concert,  produced by Michael Jackson and Lionel Ritchie, has been viewed over 27 million times. You’ll see some of the most famous legends in the music business – Ray Charles, Tina Turner, Paul Simon, Bruce Spingsteen, even Bob Dylan, who’s reading the music off a paper sheet.  You can save the link to the video and watch it whenever you need to cheer-up.
