Is there one that isn't mostly deathcore? I just want to have one I can bookmark and check out every couple days to get the shit I actually like and not have to weed through hundreds of CDs that suck. I used to use deathmetal invasion but thats gay now.

hit the drop down genre list on the side, you can probably get an RSS for death metal.
