It depends, some people freestyle but every now and then slipp in a few pre-written lines and then carry on with the freestyle. I've found it easier to do this when actually on the mic than freestyle all of it. It helps to start with a pre-written two lines to see if your flow suits the beat and then freestyle. This helps your overall perfromance cos it gives the rapper a bit of confidencecos the scariest bit on stage is just before you spit, your head sometimes goes balnk, so if you kick a pre-written first two lines, that "frightened that you'll fail feeling goes" and then ideas and fresh shit just pops up ready for you to spit. If any one agrees with this just say, cos it's good advice for people who wanna get on stage.

You can also see if someone is freestyleing because if their battling and come out with a sick verse, straight from the top of their head, after their 8 or 16 bars or 30 seconds or however long they have to spit, you can see the amazement of how they thought o that line.....you can also tell because freestyle verses are useually less complex than pre-writtenz.....exept for people with ahuge vocab EG/ Keith Murray,Biggie etc
