Which led zepplin song - Are you?

[fbd]

i dont think that this is a very good test.so far, we have 4 fools in the rain, 2 stairways, 2 loves, 3 tangerines, and 7 leeves.with the number of test takers, i'd think we'd get more results, but aparantly we only have 5 possibilities.good test idea, but just not enough results
