Never heard protest the hero but another band i find myself listening to while driving is alexisonfire.Somewhat emo-ish but good. Catchy enough to get my attention.I prefer to listen to something upbeat and fast paced. My car stereo has been dominated by Protest the Hero recently. I know, probably too emo for most here, but it's easy to sing along to and really energetic. I have a problem speeding when listening to them though.
