And REM seem to have been determined not to be. Commercial decisions not to play stadiums and not stoke exaggerated tales of excess that would make Hunter Thompson blush?

It's kind of cool how longevity has worked for the Stones while they've been so consistently second rate. Starting not remotely in the same class as the Beatles but rebels. But by 1970 they weren't in the Beatles class of rebelliousness either. Songwriting improved but it needed to and not to Lennon-McCartney levels. Does anyone much rate them above Muddy Waters, Chuck Berry, Howlin Wolf, Hendrix or even Bert Jansch? Still they persisted. Their solo projects consistently sucked no matter what talent they brought in so the Stones continued and their cultural relevance grew.

Somehow I doubt anyone will care any more about Stones songs than Jagger or Richards solo songs 50 years hence. REM may fare no better. Could be wrong, only time will tell. Jagger's lips and tongue logo was another seemingly purely commercial decision that has greatly boosted their cultural relevance. In 1995 they were deemed by Microsoft to be second choice to REM on what we might assume to be a cultural basis.
