What are some lesser known but still excellent hit songs?

Some of these might not be too rare, but some random ones I think of as deep cuts:

Fall Out Boy – My Heart Is the Worst Kind of Weapon

Four Year Strong – Flannel is the Color of My Energy (and/or Paul Revere’s Midnight Ride)

Knuckle Puck – Poison Pen Letter

The Maine – We Change, We Wait

Real Friends – Dirty Water
