All of those pointing to The Rolling Stones, Aerosmith, AC/DC, etc. should keep in mind that they aren't exactly bands coming out now. They are, in essence, legacy groups that formed in a time with "rules" for popularity a lot different than the ones that exist now, and much of their fanbases were either from that same time period or were built from generational ties to that time period. Also, sure Mick Jagger and Steven Tyler don't look like much now, back when they were first gathering their huge followings they looked a tad better.
