I tried the songs u posted, Wasnt really feeling it, I thought I would based on the image of them but o well ;)
They have some music videos and they seem good, like Big Bad Ass, thats one of the best videos personally. If they do a kabosh with Tech and Krizz its gonna be good and from what i heard from the songs from Tech and Krizz, they do a good job with the rock genre. Dirty Wormz does have a new album comin called The Mass Metal Mixslaughter. There doing songs from bands such as Korn, Killswitch engage,Metalica, Devil Driver, Powder Burn, Rob Zombie, and so much more.
I didn't noticed that, well we know who the smart one here is lol. I don' think they care. Have you seen some live footage from them
