 Stefani creates an argument between lyrical personas by alternating her vocal range and point of view . Stefani 's vocal range spans two octaves in the song , from G3 to G5 . In a melody similar to that of Weezer 's " Hash Pipe " , one side of Stefani 's personality sings in a higher range in the first person , and the other , more confident personality sings lower in the second person . During the verses , the more nervous personality discusses her concerns about leaving No Doubt for a solo career as well as the ephemeral success of female singers in the music industry . The chorus is a boost of confidence for her and continues the song 's time motif with the lines " Look at your watch now / You 're still a super hot female " . Backed by perfect octave dyads , Stefani sings a verse about her excitement for her future , and the two personalities merge into one during the coda .
