I do think it is more effective if you try to pick listening material that fits the level you are currently at.

As a beginner that’s only halfway season 2, I don’t think I will learn as much from listening to the news, as listening to japanese songs for children, for example.
With learning/practicing in general, I personally prefer to use material that is just a tad bit higher than the level I’m currently at.

Edit: To be clear, I agree that listening as often as possible is the best way to learn it. I just think you can be even more effective if you pick the right material for your current level. I learned English mostly by just reading it, watching it and listening to it a lot.
