I think the problem with people, as they start to mature, they say, 'Rap is a young man's game,' and they keep trying to make young songs. But you don't know the slang - it changes every day, and you're just visiting. So you're trying to be something you're not, and the audience doesn't buy into that.
An MC is somebody who can control the crowd. An MC is a master of ceremonies so not only can you say your rap, you can rock the party.
