5. "Un-Thinkable (I'm Ready)" (2009)
Producer: Noah "40" Shebib
Album: The Element of Freedom
In was 2009, and Alicia hadn't seen her name at the top of the charts since 2007's "Like You'll Never See Me Again." Then she took the world by storm again with "Un-Thinkable (I'm Ready)," featuring background vocals (and an verse on the remix) from Drake.
Keys belted some of her deepest lyrics to date over stirring piano chords and a thumping beat crafted by Drake's right-hand man, Noah "40" Shebib. The emotion was felt. Clearly, Alicia could still hit listeners harder than ever.
