If you liked the music in the film "Broken Flowers", some of it is available on eMusic.
That great, 60's-like tune with lazy female vocals that pops up a couple of times is on The Greenehornes' "Dual Mono" album. The tune is "There is an End", featuring the vocals of Holly Golightly. She has some albums there, too.
I also found out that the haunting Etiopian music that you hear throughout (from Winston's CD) is there. It's on Ethiopiques Volume 4: Ethio Jazz & Musique Instrumentale 1969-1974.
