Rappers who are not audible?

Personally, I love listening to raps because it's my favourite music genre but there's something I don't like about some rappers. It's very annoying when they rap in a way that you can't hear 80% of what they are saying. How do they expect me to understand what they are rapping about?

How do you feel about rappers who are not audible when they rap?

You mean rappers that you do not hear what they say or they just say inaudible words? If it is the latter I have lots of them that I have heard and I do lot like them at all.
