Jonas Brothers Song Much Better: Is it about Taylor?

They're saying that the song "Much Better" is about Taylor Swift since she wrote "Forever and Always" about Joe. The acusations of that song turned out to be true. But now they're saying that Joe's shooting back at her with this song. They're saying that it's saying that Camilla was better than Taylor. But I don't really know if that's true. Maybe it is maybe it isn't but who am I to judge.
