I personally don't think they sound like APC at all, well. Maybe the newer APC. More like Atom Ship, though I doubt they'll be known here, but I love this band. I'm typically not one for a whole lot of "nu-metal" bands, but this band has caught my interest and kept it. The Autumn Effect is a phenomenal album.
I don't think any of their songs sound like any of their other ones, but that's just my take.
