Man, I kinda had a rough idea of my top 10 but couldn't pick a #1. Its not even because he just died but I guess Warcloud is my favorite ever. I've probably played his shit the most consistently and always get something out of even his weakest verses. He dropped lots of conscious jewels and had top tier rhyming skills but never came off too serious or preachy. Love that his music is hard without being ignorant or promoting gang shit.
