Biographer R.J. Smith describes "I've Got Money" as "one of the less-known great records of Brown's career":
It's a song whose time has yet to arrive, and it's barely a song. It's like a blueprint of some uncanny object. It's an assemblage of parts: a scimitar guitar chord coming down on the One, a show band horn chorus quoting Judy Garland's "The Trolley Song," and [Clayton Fillyau's] stampeding drums. The parts are arranged in a line, one beside the next - an incomprehensible rebus.
Both Smith and Allmusic's Richie Unterberger point to the song as a stylistic precursor to Brown's later funk recordings.
