Weezer were commissioned by NASA and Apple to write a song hyping up the historic Juno mission to Jupiter. They came through with this patriotic anthem, which celebrates the American spirit in its quest to explore the solar system. Frontman Rivers Cuomo wrote on Genius
"We were on tour abroad, and it got me thinking a lot about America, which lead to me write 'I Love The USA.' When Apple and NASA asked us to be involved with Juno's historic landing on July 4th, this song seemed like the perfect fit."
