On the Kanye tip, here’s some early versions of songs and tracks that didn’t make it on the albums (but should have).

Kanye West – Livin’ A Movie
Kanye West – Home This one came out long before “Homecoming”. I think this version is as good, if not better.
Kanye West – Drop Dead Gorgeous
Kanye West – Peace PEACE!
Kanye West – Hey Mama (Early Version)
