I'm coming home again
Going back to his hometown of Chicago. Or more generally, is a metaphor for returning to his roots (of his career). Going back to the basics, starting over again.
HOME is also an acronym for four of the five Great Lakes that Chicago is surrounded by. Kanye likely learnt this in school, and it reinforces how he is returning to his roots in Chicago.
H — Lake Huron
O — Lake Ontario
M — Lake Michigan
E — Lake Erie
