Seven Nation Army's riff is one of the most recognizable in rock history — does its ubiquity make it harder to actually hear what the song is doing?

Nah. If anything, the song is refreshing in it's depth beyond that iconic riff. It's always a great listen.

Its so iconic for a reason, truly a fantastic song, the drumming by Meg, the lyrics and vocal delivery come together and paint a wonderful picture

I find its use elsewhere grating. No one needs college marching bands playing that during football games. But on record, the foundation is the melody and the dynamic range in his guitar playing elevates it. A great song and a great Side 1 Track 1.
