No, I understand why CMAR is linked to Britney. I would have a hard time with someone who thought otherwise. I think it was more of an annoyance level reaching the breaking point. And I think it also has to do wish people being all, "OMG Justin needs to move on" everytime he adds a twist to CMAR. I would imagine that he is just changing a song up that he sings all the time. It doesn't have to be about being angry at Britney. it could be about taking something that happened in his life and putting a new twist on it.
