Why? was released on November 27, 2015. After several children's albums released through the
Disney Sound label in the 2000s, this album was released on the band's own Idlewild Recordings. The Disney-released albums had a theme, such as the
alphabet,
numbers, and
science; this album was intended as a follow-up to the band's first children's album,
No!, released in 2002, and therefore had no overarching topic. "Or So I Have Read" was the first single from the album, released in October 2015. A few of the songs had been released before. "And Mom and Kid" was written for the
HBO documentary ''A Family Is a Family Is a Family: A Rosie O'Donnell Celebration
. "Then the Kids Took Over" was written for the HBO documentary Saving My Tomorrow'', but was extended and re-recorded for this album. ==Track listing==
