Off The Wall is my baby, my darling, makes me happy always, I listen to this album probably the most because I'm always in the mood for it. BUT Thriller has no weak songs, while Off The Wall has the monstrosity that is Girlfriend. Also Human Nature is Michael at his most magic, Lady in My Life at his most tender and Billie Jean just has the best bass line off all time. So the best overall would be Thriller for me.
