As a musician (one who, admittedly, wound up owing money when the bar tab was subtracted from the gate) I can't think of a better place to put them. They actually live on a line just south of the Sinatra-Beatles meridian. If you look just southwest of Sinatra, you'll see that Cab Calloway lives on the true line, with Count Basie just to the left. This would be the "dirty", less polished, and less, well, white version of the Sinatra-Beatles line (which would probably extend westward to Paul Whiteman if he appeared on the map at all).

No, the one that puzzles me is Sarah Brightman. I can understand them trying to keep her away from the cool kids, but she's got to be feeling like she got off the bus in the wrong neighborhood.

The style of music the Blues Brothers played, the Stax sound, cuts the continuum running from jazz-influenced big band risqué pop to straight-ahead risqué rock and roll. The rhythm section is from the rock world -- electric bass, guitar and piano, with foursquare beat-keeping drumming (as opposed to the sort of thing that, say, a Buddy Rich would do) -- the vocal performances are clearly in the Calloway-Prima-Charles lineage, and the horns are pure big band pop.
