What about Canibus in top ten?

How come I barely see him in top ten lists, i got really deep into his music recently and I was rlly surpriced, I mean i always knew he is a good MC but not that good... I had to get used to his voice, that isnt that comfortable, but once u get used to his voice and just listen to his lyrics and wordplay... he is so sick I might even put him in my top five.
