Talk:Epic Rap Battles of History 59/@comment-184.8.91.227-20160209003748/@comment-25263388-20160209123715

The real important thing in writing a great rap battle is having either a lot of cohesion between the material of the two sides, or having a theme that the two sides portray. The theme is generally something you see in a rap battle of contrast, whereas cohesion you see more in a battle between similar parties.

For Mr T vs Mr Rogers, you have a theme battle, with T promoting violent adult television, and Rogers promoting peaceful children's television.

For Stephen Hawkins vs Albert Einstein, you have a cohesion battle, wherein the battle is built out of the similarities between the two and the minute differences become a lot more important.

Generally, a cohesion battle results in a lot more pointed battle, raps about "You failed science here", whilst a theme battle that was a non-scientist vs a scientist would be "Your science is boring!"

Contrast and similarity can both work and both produce different battles.
