50 was pissed at Fat Joe because he got on the track New York, New York with Ja Rule (along with Jadakiss). That's why he came at them in Piggy Bank, which was a weak song. Fat Joe and Jadakiss' responses were both way better than 50 trying to diss them. Now Nas is coming at him, all three of them are better than 50. On Piggy Bank, 50 tried to say that "Lean Back" was a flop, but in reality, it was a huge hit, so I don't know what he was trying to do with that. In Jadakiss' response "Checkmate" he spits this line, Yeah, you committed a felony, but you ain't a predicate, Never the king of NY, you live in Connecticut. When 50 heard that, he was probably simply confused, didn't even know what he meant.
