Version that might exist based on comments from Travis; he said in an interview with Billboard that the song was intended for "Kanye's album" (ambiguous as to which), with Drake being considered as a potential feature (per Mano), but Travis decided to take it and transformed it into "3500" after Kanye didn't bother using it. Travis's comments suggest that Kanye never recorded any finished vocals, but it's possible that he did a mumble demo.
