Pac/everyone
2Pac can adjust accordingly, but still keep his own style and rap and flow to almost anything. So imo, 2pac can adjust to any type of song basically. Weather it be just adding adlibs in the backround, or dropping down verses.
Though this thread clearly states "RIGHT NOW", I'd say put QD3, and DJ Quik up with a few main stream rappers that are popular rigght now and make even bigger hits!
