The last thing you should do is shutup about it if they bring it up. Letting them have their way and you not saying nothing is sort of like a contribution. If a black person was to be in a room and have white people clowning the black race, if the black person was to not defend his race, then that is also a contribution.
You got to let them realize that pac is so great because no one has the body of work he has-meaning a whole lot of quality in his quantity and that no other mc rhymes from the heart. If your friends are the type of friends that like 50 & D-Block, then make a cd full of hard pac songs that they can relate to. If they like deep songs, then make a cd full of deep pac songs. If u and your friends are in your teens, I suggest you play more hard/raw pac songs since most teens like agression. Whenever they are in your car or whether they come over to your house, you have it blasting until they get tired of the songs.
You have to put people who think pac is overrated onto songs that may not be as popular or songs that they might not be familiar with. If your friends aren't up too much on pac, I suggest you put away the more popular singles such as Changes, Keep Ya Hed Up, & Dear Mama away.
Songs like, Troublesome, Who Do You Believe In, Hit Em Up, Ambitionz Az A Ridah, Thug Style, Lil Homies OG, This Life I Lead OG, Life As A G OST & OG, High Till I Die.
