In comparison to how long they have been singing, I know relatively few of their songs. Out of the ones mentioned, I have only heard Walk This Way and Dream On.
Walk this Way with Run DMC is a great song. Don't Wanna Miss A Thing, cliche song but it's great. Except for the odd screaming at the end.
Dream On, Falling In Love is Hard On The Knees, and Crying. You should see the version of Crying on the movie Be Cool. Sweet movie.
