Hello!
I have played guitar and sung for many years, and am pretty new to keyboard.  I am working on getting fluent with left hand chords in all keys.  At the moment I am working on switching vi-II-V-I changes to all keys.  Am7 to Dm7 to G7 to C, for example.   
Can any of y'all recommend some songs using these changes that will help me learn?
