Its not that there aren't Led Zepp or Pink FLoyd or The Doors or any other mega bands songs that could be on this thread, its just its hard to choose which ones NOT to link.
Some songs became over played by radio in the time since their release that justy linking them is a cliche
Hotel California
Stairway
Bohemian Rhapsody
Money
Comfortably Numb (though it pains me to admit it)
Money for Nothing
Those are the big examples I can think of but there are more. They aren't bad songs, they just got over played in the time since their release
and then some songs aren't ever played full length on radio and survive
