What is that shit called? Thrash? Death?
Being a bit of a metal head, most folks will call it Death metal simply due to the fact that the singer (if you can call them that) is growling, screaming or whatever the hell you want to call it.
You have to keep in mind however that there are a lot of singers out there who growl but can actually sing if they want to (Think Slipknot as one main stream example). When they growl, they sound like a Death or Thrash metal band but when they sing, it's anything but.
If you want to hear some current examples of bands that are true death metal, check out:
Decapitated
Opeth
Avulsed
Anata
Obituary
I can give you a lot more but those are decent examples.
Thrash to me is something entirely different and is night and day from death metal. To a lot of people thrash metal is bands like Slayer, VoiVod and yes even Metallica. I honestly don't think that those bands fall into the thrash category. Thrash to me is more along the lines of bands like Overkill, Sepultura etc but it's debatable.
I prefer what has become known as melodic rock and melodic metal as it offers up the best that Rock and Heavy Metal have to offer. Bands that I would classify as melodic rock or melodic metal bands are:

If you want to hear some great examples of some straight ahead rock bands, check out:
Gotthard - (If I could sing, I would like to sing like this dude!)
