John Legend co-wrote and co-produced the bulk of the album, working with collaborators such as Kanye West, will.i.am, Raphael Saadiq, Craig Street, Sa-Ra, Eric Hudson, Devo Springsteen, Dave Tozer and Avenue.

The album has a range of influences, from soul to hip-hop to classic pop to alternative.

I just tried to do it with the highest standards of quality."
