Jeff, your picks are nice looking, but I think the SMA has to be an A-list or instantly recognizable name. (Blake Shelton barely fits that requirement, if you ask me, but I gather he's famous in some circles.)
I take your point, but, see, there you go. "I gather he's famous in some circles." Blake Shelton isn't famous to you because you don't watch
The Voice (at least I assume you don't) or listen to Country Music (I assume you don't do that either, unless there's something you aren't telling us
). To people who do both, I'm sure Blake Shelton at least qualifies as A-List and instantly recognizable. (I don't do either, but I do watch TV, so I know who he is. I see him all the time in commercials for
The Voice.)
I think my guy David Boreanaz is the same deal. To fans of
Buffy the Vampire Slayer, and they are legion, or all the folks (like me) who watched him for years on
Bones, he is instantly recognizable and I venture A-List to them.
What I'm saying is, I've come to have the feeling that A-List is in the eye of the beholder, or at least depends on the perspective of the beholder.
