"College Dropout" is supposed to drop somewhere between late January and early February. It's been delayed several times, and I hope the current anticipated date of release will not move down anymore.
There is an advance/promo floating around the intarweb. You can also catch a lot of the songs that are on the advance/promo on the many Kanye West mixtapes that have been released over the past year, such as: Akademiks Jenious Level Mixtape Volumes 1 & 2, Chi Town Classic Volumes 1 & 2, Behind The Beats With Kanye West, I'm Good, and Get Well Soon.
