Yes, UTW, you are correct, the least underrated. The winner should be the song that is the most underrated Eagles song.
I hope no one faints that I'm playing along. The overall premise is to 'vote things off the island' and there's too much I love about the Eagles to be voting against things. However for this particular game, most of these songs either do nothing for me or I actually dislike them, so I have no problems 'voting things off'.
I am going to use the logic Soda used for LROOE, and vote for The Last Resort. The song has had too much acclaim to be considered underrated in my opinion, and given my thoughts on the song, I feel that acclaim has vastly overrated it.
