So, what you're saying is if the songs gets better with people helping them out, they shouldn't get that help because "we're blink god dammit. We have to show everyone that we can write without Tom.." ?
Or are you saying that you won't enjoy this album if there are other persons besides Mark, Matt & Travis in the credits !?
Seriously, who the fuck cares? A good song is a good song no matter who is singing it, or has written it.
