Well, it is of course all relative, but I can try to do a Nicomachean Ethics sort of thing here:
Soul: James Brown
No Soul: Barry Manilow
Middle-of-the-road: Lou Rawls
Soul: Shirley Bassey doing the theme song to the film Goldfinger
Soul: Paul McCartney doing the theme to Live and Let Die
No Soul: Rita Coolidge doing the made-for-Muzak theme to Octopussy
Hunt Her Down And Kill Her: Madonna doing the theme to Die Another Day
Soul: I’ve Got You Under My Skin, from Sinatra at the Sands
No Soul: I’ve Got a Crush on You, same album
Burn In Hell Sinatra, You Bastard: Count Basie putting up with Sinatra talking mush mouth on the same album. Note: Basie could have slapped the Chairman of the Board around in the dressing room, for all we know, so this might rate an “indeterminate.”
I leave it to the experts to line up Mel Torme, Tom Jones, and Tony Bennett. Perhaps they’re all walking the line between something and nothing.
Devo, is a classic, plastic, soul-less band. I believe that it was their intention to drain every last drop of life from their music until you start to think, “hey, maybe they are robots.” Nevertheless, I love them so.
Any pop music which slips a childhood “na-na-na-na-nyah-nah” scale into the vocals is by default contemptible bullshit.
A jingle makes you want to sway your shoulders and snap your fingers: I’m a Pepper, you’re a Pepper, he’s a Pepper, she’s a Pepper, wouldn’t you like to strangle Manilow in his goddamned sleep?
Music with soul makes you want to swing your ass.
I’m sure I’ve helped not at all, and annoyed others. What do I know anyway?
