Yeah, I think whoever it is would have to had defined an era, sold kajillions of records, inspired a thousand good bands and 100,000 terrible ones, written inescapable songs that everybody knows whether they know it or not, and made the chickies whet their panties. Only Zeppelin really qualifies. But ABBA's not a bad choice, either, except they were all couply and Swedish and shitt so no whet panties (sorry, Andreas).
