So, it is up to me to pass judgement on this one!
And I must say, damn this is hard
Both songs are great and stem from great albums.
I really like Dead to the World and it's classic NW vibes with great Marco vocals. My vote, however, still goes to that song, resulting into the survival of Song of Myself (that is how this works, right?). I think Song of Myself serves a more unique spot in the NW library. Not too fond of extensive spoken words parts in general, but Song of Myself is a kickass song of about 7 min prior to it's spoken section. And in respect of the concept album as a whole, the second half works really well.
