 When they met , Akon played some of his tracks for her . They thought about words that would suit the marketing of Stefani 's music and her clothing lines L.A.M.B. and Harajuku Lovers , settling on " Sweet Escape " . Akon played her the beat he had developed , and they began working on the song . They wrote it in 10 minutes , coming up with a doo @-@ wop song rather than the hip hop sound Stefani had expected .
