So because of Borderlands 2, I learned about Nero. Namely their song Doomsday, which was released all over the BL2 Joypuke trailer. I finally managed to get out and buy the album Welcome Reality. While there's a few tracks on there that don't really do anything for me, I honestly found it to be pretty enjoyable. I ended up listening to the whole album on repeat/shuffle a few times while I did various stuff online, and it's very, very listenable. If you guys haven't tried their stuff yet, but love dubstep, it'll probably be a pretty solid addition to your collection.
