T-Pain has announced a new mixtape called "The Heath Ledger Project," explaining the meaning to Rap-Up he says:

“Well, you know how he died. He kind of went crazy because he was so into being the Joker. After they finished shooting [The Dark Knight], he couldn’t stop being the Joker. I think he went so crazy trying to master his craft that he died for what he loved doing. He died mastering his craft.”

However the music will not necessarily be dark, “It’s going to be called The Heath Ledger Project because that’s how much I love music,” he explains. “That’s how much passion I have for music. I want to master my craft like [Ledger] tried to do before he died.”
