Yes, but that may also be because of more modern technology. Radio was far more common for Muddy Waters (not to mention John Lee Hooker (but I will)) than for Robert Johnson.
That's entirely my point. Muddy had the advantage of being in his prime during an age when technology was able to spread his music to a wider audience. He was able to reach more people, and therefore more people were influenced by him.
I'd still place Robert Johnson and Satchmo at the top of the list, but Muddy can't be a distant third.
BTW, Coltrane and Miles should be there too, as mentioned by others. Miles, by virtue of his ever changing style and move into progressive jazz and rock probably influenced more musicians than did Coltrane. Of course, it's a judgment call.
I'm sticking with RJ, LA and MW...
