What am I listening to and where can I find more like it?

[SuckerPunch]

Hello!
This is my first time here in the music forums so if I am meant to be posting this is some sort of "recommend some music for me" kind of thread I am sorry.
Now that is out of the way I will go on.

As the white boy I am I mainly listen to bands like Megadeth but recently I have started to hear some music that I [b]really[/b] like but I have no idea what genre it is or anything.
Examples of this: (I love all these songs all the way through but you can just skip to the time specified if you wish)

around 1:21 specifically

around 1:51

What genre is this?
Where can I find similar tracks?
What bands should I look into?

Well, the first one is chiptune, and the second two is drum and bass(DnB).
I see what you are looking for more specifically too, but I'm not very familiar with this kind of music so I can't help you.

song #1 is basically an 8bit song, or could be considered a keygen song, what keygens play when you have them open. don't know of any artists who do this type of music primarily.

#2 is Drum and Base, if you like that try Deadmau5 and Pendulum

#3 is also DnB, I suggest you go check out Dubstep also, it's a type of subgenre of the whole "techno" genre. Excision and Dastik are both very good producers.

Since when does Deadmau5 do DNB

bleh, I don't know, it just kind of feels like it, pretty good artist though anyway.

maybe not, I don't know what I'm talking about when it comes to deadmau5, ignore that part.
