Just watch a video of them on Youtube. Watch how they make their guitar riffs look extremely hard... They always make that "this part is complicated" face when they are playing. But, if you take the time to actualy listen to the music it's the same basic notes over and over and over again.

DE: Look at this crappy band, I want to fling shit at them.
DS: Oh yeah! Nickelback bites the big one!
