And I think the answer is "yes" in most cases. Obviously they're not quite as old *yet* but I think we're at the point where a lot of those listed in this post are considered "legacy acts" as opposed to currently-relevant artists.
And IMO it seems that Snoop, Cube, Jay, etc. are getting the same type of love and respect on a universal level that the Stones et al have always gotten.
Plus when they tour they're gettin similar $$$ too it seems, based on ticket prices haha.
