frankie miller, high life-- overlooked white soul belter who clearly influenced rod stewart and bob seger, though i think he's a better singer than either. does pretty well with the songwriting, too.
elvis costello, the delivery man--for my money his best post 80s record, mainly because he tries harder to be a rocker than a crooner
willie dixon, i am the blues--it's curious he never shows up on the GOAT songwriter list. i generally prefer his takes on these classics to the heavyhanded doors/cream/zep covers.
