A whole bunch of early Bill Withers hits. Great song writing, and what a voice. Learning some tunes and trying to get some of that bluesy thing he has into my stuff. Songs I've been studying:

Ain't no sunshine (of course)
Grandma's hands
Use me
Who is he (and what is he to you)
Everybody's Talkin (originally buy Nielsen I think)
I Don't Want You On My Mind
