1,000 Musicians Cover Rage Against The Machine

Over the weekend, 1,000 different musicians came together in Frankfurt, Germany to cover Rage Against The Machine’s “Killing In The Name Of”.
The performance, which can be seen on YouTube, was the latest effort by Rockin’1000, a European organization that puts on a different massive performance each year.
Billed as “the world’s largest band”, Rockin’1000 began in 2015 when they gathered in Italy to play the Foo Fighters’ “Learn To Fly”.
Other artists covered in past years include David Bowie, Nirvana, Queen, and Hole.
What song should Rockin’1000 cover next? Would it have been even better with 1,001 musicians?
