Bone Thugs n Harmony stole Chief Keef's Swag and are in the Illuminati aka Bone Thugs n Harmony sucks and you should listen to Chief Keef: Difference between revisions

And speaking of rapping fast, that's another thing BTNH ripped off from someone else.  There are basically two things they are famous for, the singing/rapping style and speed rapping.  But actually they can't even claim credit for the latter.  The speed rap style was pioneered by Chris Brown and Lil Wayne and only later immitated by BTNH, Twista, and Tech9ne (badly, I might add).  There is also an awesome verse on Big Sean's "Ass" where he does some mad speed rapping.
