I can do a "personal" top ten but that's about it.
This is strictly for songwriting.
1. Gordon Lightfoot
2. Bob Dylan
3. Jim Morisson/Bobby Kreiger (Bob wrote Light My Fire not Jim).
4. Paul Simon/Art Garfunkel
5. Mariah Carey (except for cover songs,she writes and sometimes produces her own.)
6. Paul Williams ("Old Fashioned Love Song",
"Out In The Country","Evergreen",
"Where Do I go From Here",
"Another Fine Mess",
"What Would They Say?","Rainbow Connection").
7. Harry Chapin
8. Steveland Morris (Stevie Wonder0
9. Any member of Fleetwood Mac
10.Al Stewart
I know,a couple aren't living but I couldn't think of any others offhand.
Not set in stone,mind you,but that's about the gist of it.
