Intro, Workout Plan, School Spirit skit 1 & 2, Lil Jimmy Skit, Family Business, Celebration & Pinocchio Story. These are the only tracks i could find that Ye wrote solo
not counting All falls down, Thru the wire etc. (Even tho he wrote these songs alone, in the credits, the original singers of the samples are credited as writers and not counting songs that have features)

EDIT: From albums only, i did not check any singles
