Sources close to Meek tell us he was not referring to Drake in "Dreamchasers 4" -- "I can't wait until we run into ya. Ima put a gun in ya."
We're told Meek is insisting he wasn't talking about anyone in particular ... it was just a lyric.
We're told Meek is trying hard to stay on the straight and narrow because he's under a microscope in his probation violation case.
Meek might have considered ... a better idea would not be to threaten gunfire, even in a rap song.
