Sorry, Patrick Mahomes ... you might be the NFL's top QB at the moment -- but Chiefs legend Tamba Hali tells TMZ Sports it ain't enough for him to write a song about you!!
ICYMI ... Tamba's working on going from NFL superstar to music icon -- having just released a legit album.
And, with Mahomes tearing up the league -- he had more TDs (6) than incompletions (5) against the Steelers -- we figured it'd be a match made in Chiefs heaven to hear a Hali-Mahomes song.
