Paul Wall and Chamillionaire had a falling out after years of working together, which "The People's Champ" emcee spoke about with VladTV. The Houston rapper told us that it was the verse, "Paul Wall and that Koopa still ain't talking/Money speak, all that bulls*** keep walking," on Pimp C's "Knockin Doors Down" track that led to their reconciliation. Paul explained that Pimp C had a talk with him about ending the beef, but it was the track that pushed him to end it, because "it put [our beef] in the public eye and we couldn't run from it." 

During the conversation the "Sippin Out the World Cup" emcee spoke about linking back up with Chamillionaire for a new album, but he emphasized that the timing and project had to be right. He also pointed out that Chamillionaire isn't hurting for money to do an album, as it was recently reported that the "Ridin Dirty" rapper invested in a tech company that sold for $500 million.
