ice burgundy (bricksquad) takes dre lines wholesale and verbatim and puts them all in over his raps and i haven't heard him say the words 'MAC DRE' ever in his raps. i fuck w/it.
dre was functioning with these foos big homies in the feds in the 90s some of these dudes put their youngsters on game and they became rappers. guarantee dre had connects in LA, new orleans, atlanta, miami, ny, north carolina, DC, etc. dre was the type who's reputation as a rapper and a gangster proceeded him everywhere he went people wanted to get down w/the bay guy and that shit gets passed around. diggs the same way too.
diggs and dre legend in the penn and in the streets is bigger than their rap fan base and rap career for sure and that's why you see people shouting them out that on surface level seems weird
