Agreeing and desagreeing!!!

Clàudia : What do you think of this Jonas Brothers CD?
Berta: I like it. I think it's OK.
Laura S: I agree. I also think is fantastic.
Berta: Well, but I prefer rock and roll.
Clàudia: I agree with Berta. But their last CD was better.
Laura S: Yes, I suppose you're right.
