I can't see it here but I would pick misty mountain hop. also I love tangerine and hey hey what can I do. but choosing one led Zeppelin song is difficult enough because they have so many great songs.

SINCE IVE BEEN LOVING YOU!!! but only right now lol I bet it'll change in a week...or tomorrow...I also like Fool in the Rain...so many memories! Dazed and confused, black dog hehe
