[above1]It's so easy to get enamored with beef, especially on the rap front. We've watched titans like Pac and Biggie, Jay Z and Nas, 50 Cent and Ja Rule clash on numerous occasions. While we've ravenously watched these battles, other feuds ensued in the world of R&B. Recently, we've watched Kevin McCall and Chris Brown bump heads, after being buddies for so long. We've always tried to tell you guys: don't sleep on these R&B cats, because they know how to get busy too when it comes to beef.
