Sigh. Blink 182 and Sum 41 aren't really punk rock. It's pop punk at best, and I'm being extremely generous with that statement. :/
You want real punk rock? Listen to the classics: the Ramones, the Stimulators, the Sex Pistols, and most especially the Clash.
A newer band is Bantoom Rooster. They're pretty good.
Anyway, I've recently started listening to the Artic Monkeys. They're good.
