A7X isn't metalcore anymore. Their first album was the only one that was really metalcore. I don't get the hate that band gets, I remember hearing them for the first time and thinking how refreshing it was to hear a band with melodic guitars, and real singing. Opposed to stuff like Lamb of God and Slipknot who were barely melodic and always growled. That said, I only really like one of their albums which is the selftitled one. I remember when that album came out they were playing nearly every song on the radio. I think there were 5 singles from that album. As far as new bands go, that was probably the first really classic album of the last decade. Every song was a potential single.
