Agree completely with Springsteen, Prince, Byrne, and Westerberg.
Others I would nominate, in no particular order:
Elvis Costello
Marshall Crenshaw
Tom Waits
Grant McLennan/Robert Forster (Go-Betweens)
Bob Mould/Grant Hart (Husker Du)
d boon (Minutemen)
Lou Reed (his best solo work was done in the 80s, IMO)
Finally, Lucinda Williams first came on the scene in the 80s, but did not produce her best work until the 90s. She is at or near the top of my list of top songwriters of the 90s.
