Stairway to Heaven (Led Zeppelin) of course... One of the greatest songs.
Hotel California (The Eagles) is also a good one, and will be remembered. Several songs by Queen such as We Will Rock You and We Are The Champions, will be remembered for a very long time.
Money (Pink Floyd), I will not forget that one! Stray Cat Strut (The Stra Cats) .... Free Bird and Sweet Home Alabama (Lynyrd Skynyrd) ... several songs by
CCR ... NUMEROUS Beatles songs (Twist and Shout, hehehe.. yellow submarine, penny lane, hey jude, strawberry fields, etc etc)...
So many I can't even think ..
Newer people .. Well, sadly I can't think of many new bands taht will be remembered. Perhaps the red hot chili peppers, i think they have good talent and will not be forgotten.
Oasis (which somehow always reminds me of the beatles) pretty much has "Wonderwall" going for them, it is a good song ... but I don't know too many more by them that will be remembered for long.
Green Day will most likely be forgotten quickly, except for maybe a couple memorable songs that may stick around (Hitchin' A Ride, Brainstew, Time of Your Life).
Goldfinger is really good IMO, and will probably be remembered... Blink 182 will be remembered but not as a good band in my mind (come on, when you hear songs like Adam's song and Dammit, you gotta think .. did they get a small child to write that music?). No offense to any blink lovers, and please don't flame me.
I will stop now...
