What Kind of Drum and Bass is This Style?

I'm a huge fan of drum and bass, it's pretty much 90% of the music I always listen to.

I have noticed though, that I like a specific KIND of drum and bass, and cannot for the life of me remember what this type of D&B is called. I know that there's different sub-genres of D&B, such as jungle, sub bass, liquid dnb, grime, vocal, etc.

And the kind of D&B I enjoy is very very different from ambient or liquid styles. Was wondering if somebody could tell me what the style I like is called.

Here are some samples of the style of D&B I enjoy, so you get an idea. The styles made by Pendulum are probably going to be very different from the styles made by DJ Fresh, and so forth.
