It's the song Spencer Pratt  was too embarrassed to release  -- an incredibly nonsensical attempt at  rap about chicken wings ... counting eggs ... we have no idea ... but  worst of all, it's actually not THAT bad.
The details around the song  are pretty fuzzy -- but we're told Spence recorded it at an L.A. studio  last year ... and he was so ashamed of the final product ... it never  saw the light of day ... until now.
A sample of the lyrics -- "Money ain't a thing / Nothing but a chicken wing / Call me Mr. KFC / S dot P in the flesh."
