Babyface Ray Says Cade Cunningham May Be Detroit's Next Big Rapper!!!

Babyface Ray has been an integral part of Detroit's hip hop stock rise in the past few years and he isn't being humble about his contributions ... he's carving his own name on the 313 Mt. Rushmore!!!

TMZ Hip Hop caught up with Babyface Ray outside LAX this week and he tells us he fits all the criteria to be immortalized in his city -- along with Eminem, Big Sean and the late Blade Icewood for his Mt. Rushmore picks.

And just like Sean, Ray's also delusional hopeful that the Lions and Pistons will win championships next year!!! Gotta root for the home team.

While Babyface did acknowledge Detroit would need a few hundred Mount Rushmores to properly honor its music history, he reveals he's excited to hear from a most valuable transplant ... Pistons star player Cade Cunningham!!!

Ray says he and Cade have a mutual studio engineer and he's been told the stuff in the vault has been fire ... so it's only a matter of time before they cross-over styles.
