Greatest Songwriter of all time


I was reading the Dylan post and it got me thinking. There are many great songwriters that come to mind, my expertise/knowledge is primarily with rock music. If you could only pick three, what would they be? My vote for best lyrics goes to:

Jim Morrison
Bruce Springsteen
Elvis Costello

Best music goes to:

Mark Knopfler
Stevie Ray Vaughn
Frank Zappa

cfb-Yes, I have "Poet" also, quite good. I know TVZ didn't write any of the songs on "Cold Dog", but I thought some of the songs GC wrote on it were about, and a tribute to, TVZ. I also recall an article ( S'phile?) about CDS about a year or so ago re same. But then again, the neurons aren't synapsing like they once used to. Age? Possibly. Posited smack dab in the midst of divorce? Naaahhh :-)
Oh yeah! I forgot to mention 2 other best rock-poets:
David Byrne, Pete Sienfield.
I can't resist these parlor games. For the sake of simplicity, I've ruled out the twin tower tandems of Lennon/McCartney and Jagger/Richards.

Hard to narrow it down to three, so how about these groupings?
