Freestyle for me will always mean off-the-top...Thinking it up as you go along whilst keeping the rhyme scheme, flow and delivery consistent...
It's also used for people who basically put all their throw-away bars into one long verse and just drop them randomly...
Examples of Freestyle - Eminem competing in the rap olympics...
Examples of
NOT Freestyle - Eminem's Retarded Kid
Freestyle...
I think they should come up with a new term for not off-the-top Freestyles...
Freeverse perhaps lol...
..."Yeah dude did you catch the new Midnight EyeZ Freeverse!?!?"...
I think it could catch on lol...
