What is this song? Rock/Metal?

It's a somewhat fast/heavy sounding rock/metal song, with primarily male vocals, with female vocals that start in the middle, that sound a little bit like Amy Lee, but I'm pretty sure it isn't her. I heard it on the radio a couple days ago, but never caught the name of the band, or the name of the song. I can't seem to remember any of the lyrics either, which would make the search A LOT easier. If anyone can help out, I'd greatly appreciate it.
