As you guys already pointed out. GOAT is truly an opinionated statement and arguments can be for different reasons. Personally, I've never been able to break it down to just one or two GOATS. My mood swings back and forth on what i want to listen to at any given time. However, the artists included here are consistently at the top of my list. Here's a list (in alphabetical order) of my Top 20 plus eMCee's of all time. I did not include Thes One & Double K, since their presence on such a list is a given round here.
