It sounds a lot like the tension that results from being 19. You are pretty much ready to be living on your own, or to go away to school. These types of conflict will likely increase until you move out. But it isn't a bad thing because that day is coming soon.
Because parents are older, there is a tendency for them to be more set in their ways. Negotiations to change preferences and lifestyle tend to veer in favor of those more entrenched. Also parents have a history of being in charge over their children, so even that can be a habit.
In short I'm saying, that at least it is a short-term problem in a practical sense, but is not terribly likely to resolve itself in the current scenario.
