"Something's Missing" is a song by John Mayer. It is the third track from Heavier Things, Mayer's second studio album. This song is distinct from all other songs by Mayer as it is the only song to have appeared on every live release Mayer has contributed to, including the live album, Try!, from his group John Mayer Trio. Mayer has mentioned (even in his Grammy acceptance speech) that his song "Daughters" wasn't suitable as a single. He has mentioned that "Something's Missing" along with "Come Back To Bed" would have been more suitable as the singles from the album, despite the success "Daughters" earned him.
