"
What You Waiting For?" is a song by American singer and songwriter
Gwen Stefani from her debut solo studio album,
Love. Angel. Music. Baby. (2004). Written by Stefani and
Linda Perry, the song is the album's opening track and was released as Stefani's debut solo
single. "What You Waiting For?" details Stefani's lack of inspiration, fear of producing the album, as well as her reaction to pressures exerted by her record label. It is primarily an
electropop song and introduces Stefani's four back-up dancers, the
Harajuku Girls, who had a major input into the album's production.
