Yeah dude, afi is the shit. I love them.
I'm sorry but those bands aren't punk. I mean they aren't fully punk their pop/punk. Pop/punk is the worst music ever. No offense Jewelz but all of them but The Used suck. The Used are pretty good. If you really want to get into punk music then try some Ramones, afi, Sex Pistols, and maybe some Rancid. Rancid is pretty good. Atreyu is also good.
