Genres must be judged on their terms. Just as we have with recent country and latin-pop charts, this week we grade Billboard's top 10 rock songs. The '90s are owning! The top three songs are the Last Man Standing of rock: nostalgic, familiar, and unsurprisingly resilient.

1. Foo Fighters, "Walk"

This is a VERY generic Foo Fighters song. Those are Foo Fighting words but I can't get too excited about the ultra-compressed go-get-'em alt-rock crunch of this song because I've heard it so many times already before. It gets a lot better toward the end when Grohl starts screaming about how he never wants to die. Grade: B
