Hey guys, I was hoping you could help me out by telling me some songs that are very known. You know, like songs that if you play in a mall, everyone would know, even if they don't really listen to rock.
Deep Purple- Smoke on the Water

Everybody and their sister should know what song that is.
WTTJ, SCOM, Don't Stop Believing, Master Of Puppets, Cowboys From Hell, Cat Scratch Fever, Another One Bites The Dust, Bohemian Rhapsody, Fat Bottomed Girls, We are the champions, we will rock you, Raining Blood, Black Hole Sun, Free Bird, Sweet Home Alabama, You Really Got Me, Jump, Runnin With The Devil, Eruption.
Obviously Fassa.
Well thats a pretty general question but nethertheless here are some that haven't been said

Iris-goo goo dolls
welcome to the jungle-gnr
sweet child o'mine-gnr
good riddance-greenday
viva la vida-coldplay
are you gonna be my girl-jet
