The Biggest Band in the World

In an effort to teach myself more about classic rock, I've been listening to some Led Zeppelin. I like it a lot more than I thought I would. My favorite songs thus far, in no particular order are:

Ramble On...Led Zeppelin II, 1969
Heartbreaker...Led Zeppelin II, 1969
When the Levees Break...Led Zeppelin IV, 1971
Black Dog...Led Zepplin IV, 1971
Babe I'm Gonna Leave You...Led Zeppelin, 1969

and of course the classics like
Rock and Roll...Led Zeppelin IV, 1971
Stairway to Heaven...Led Zeppelin, IV 1971

So I guess I liked 1971 the best, so far! It's a lot of music to absorb so there may be more favorites to come.
