I think The Rolling Stones HAVE to be in this, frankly...
They are one of the very, very few bands that could lay a legitimate claim to being the BEST rock band of all-time...only a few others could challenge them for that, and I'd argue that outside The Beatles and maybe, in some circles, Queen, no band's had a larger impact on the musical and cultural landscape of the last half century.
The Stones are good to the point to where they ARE part of modern Western culture, as are The Beatles, Elvis, Bob Dylan, and a few others.
I'll make sure they get in...if I absolutely have to, I'll sacrifice Billy Joel...
But I appeal to others here--surely there's a band/person here that's less deserving then Billy Joel or The Rolling Stones?
Of the others on the To Add List, I'd argue Ray Charles (biggest name in his genre, jazz) and Michael Jackson (the biggest name in music of HIS era) need to get in...the rest I'd really like to see the others make it too...
But I'd argue The Rolling Stones, Ray Charles, and Michael are essential to a "Best of" for Music here.
