@laurel I'd love to reply to the pop v. punk distinction, but I fear I might accidentally drop in a postmodern philosophy reference, so we'll leave it be. NO FAIR CITING AN AUSSIE FRIEND (Arguing by authority!)
Provocateur Chuck Eddy once correctly described AC/DC (I paraphrase from a hazy memory) as the most punk band next to The Fall. (I think the latter has more staying power). That said, I wish AC/DC (the ultimate singles rock band) insisted on full length downloads only, just to screw with people.
