It's the kind of song that is called a "standard," or if it's not, it's exactly like the kind of song they call a standard--a beautiful melody set against an unpredictable chord progression, but usually with a very conventional song structure--verse, chorus, verse, chorus, bridge, etc. The beauty of the lyrics is in how they're delivered and not necessarily just in the words themselves. For instance, I give you this:
I’m in love again
And the feeling’s not new
Yes I know the signs
And I know what to do
It’s a highway
that I have traveled through before
So I know all the curves
and I’ve come back for more
I’m alive again
I can wake up and sing
Nothing bores me now
I enjoy everything
Here I go again
The way that I always do
Cause I’m in love again,
All over again, with you
Well, all that? and these facts--that Peggy Lee came from North Dakota, and her name was Norma Dolores Egstrom; her home was a violent one, and she started her career as a singer when she was just a teenager; that she wrote lots of music and in some ways shaped the delivery of more than a generation of female singers--and something something about how amazing Dianne Reeves is--all of that will be a poem, maybe. Right now, it's called "Everything." Or maybe "--everything." Don't hold your breath, though. It might take awhile.
