Cover art for America lyrics by Imagine Dragons

To the tallest of the towers that fall and rise 1-7-7-6

~The tower that replaced the twin towers in New York City was capped at 1776ft It is now the tallest building on the North American Continent.

"The names upon the list For all the ones that gave until they died"

That could be talking about the people who died in 9/11, especially the firefighters and other first responders. It would fit with the theme of the song.
