I meant that it's not punk in the traditional sense; I know that hardcore is a subgenre of punk. Saying that there wasn't anything punk about it was definitely an exaggeration on my part, but I still feel that pop-punk differs from melodic hardcore/emo enough, that it's wrong to so confidently label the song as such.
Especially if there is such a thin line between one style and the other - that just means there are little things separating them, but they are distinguishable details regardless. I can see what you guys mean, though. The main riff could pass for emo or pop-punk, so it really goes either way. I think it's cool how Envy put their own spin on the pop-punk thing, though.
