Lyrics Got a Thing on My Mind - Sharon Jones and the Dap-Kings

I Got A Thing On My Mind
I'm sure I'm gonna find it
(Bis)
Don-t let nobody tell me
My thing it won't comme true
'Cause I ai'nt lyin' down
'Til I get my dues
[Refrain]
Now good things don't come easy
Lord knows that I've tried
Cause I got what I got
Cause better folks I've got (?)
[Refrain]
Désolé, mais le 3ème couplet m'échappe...
