There is a lot of rap samples on Best Service's "Hallelujah" library. But I'm not too familiar with either of those composer's works (i.e. I can't think/don't know of any songs they've made that has rap samples). Razakin wondered about rap samples as well though. I can try checking with him on what's in the library.
Edit: Razakin mentioned Star Ocean 3 specifically as well, when he linked me a couple of songs with rap samples. I actually found all of the rap samples from Bitter Dance in the Hallelujah library (huge list below):
