Here are a couple of more song writers I just thought of that I personally like what I have heard from them:
Ray LaMontagne was born in ’73 and according to Wiki his first CD was released in ’04 and since then he has released at least seven more "studio albums" and some EPs and some singles. I say "at least" because it appears to me as if the wiki article is a bit dated. I slowed down considerably on buying CDs in the post 2001 world, but of the two of his I did buy, the one I like the most (and it is up there on my rack where I keep my favorite go-to CDs) is God Willin’ & The Creek Don’t Rise.
Mia Doi Todd was born in ’75 and her first two CDs were released in ’97 and ’99; After those two, and up until ’21 she released nine more "studio albums" and some singles and two "remix albums" and one soundtrack (Music for A Midsummer Night’s Dream 2018). (I do not know if she has any post ’21 "studio albums".) As I’ve typed previously, I do not listen to the radio much any more nor do I buy many CDs these days, but on one of the rare times I was listening to the radio and hearing her sing My Baby Lives In Paris, that was enough for me to buy Cosmic Ocean Ship and in my opinion the CD is made up of solid writing.
