“Fab may be the best R&B–rapper] of all time,” J. Valentine said.

"Nobody raps on R&B better than Fabolous," Tank agreed.

"I am willing to agree with that," Valentine confirmed.

It is no surprise that Fab liked what he heard, and he posted the conversation.

Are they correct?

How about rappers like Wale, Drake and Rick Ross?
