shit there could have been loads of singles,i'm pickin the tracks wit the best lyrical content cause beats can always be changed.
never call u bitch again - it would be a 2nd or 3rd single.
street fame - for the streets
friends - for the streets and clubs
still ballin - release 1 with kurupt and a dre remix feat snoop,kurupt,quick,e40 it would have brought the west coast back.
homeboys - solo if there is one,people i know who dont really listen to pac but rate cause of songs like this where spits the truth.
there are loads of others like but off top of my head thats what i would choose
