I need some good hip hop songs fast??!?

I'm makin a cd for my cousin. So far, i've got arab money by busta rhymes, get your freak on by missy elliot, you can do it by ice cube, the next episode by dr dre and snoop and put you on the game by the game. As you can see, she likes fast-paced hip hop music with a good beat. Not heavy b, but something that has a good fast-paced beat Please list some more songs like I have provided. Thanks
