Together with their record company they had commissioned mixes by Todd Terry (who had turned Everything But the Girl's " Missing" into an international club anthem). Blending elements of electronica and dance music, they are best known for their UK top 10 singles " The Time Is Now" (2000) and " Familiar Feeling" (2003), as well as the 1999 Boris Dlugosch remix of " Sing It Back" which became an international hit. It first appeared in its original version on Moloko's second album, I Am Not a Doctor (1998); it was released as a single on 8 March 1999, reaching number 45 on the UK Singles Chart. The remixed version was eventually featured on over 100 compilations, and was later added on Moloko's third album, Things to Make and Do, after hitting the top ten on the UK Singles Chart.

Murphy had started writing the lyrics while clubbing in New York City, [3] and knew the song was at heart a dance track, but the group wanted to record it in a different artistic fashion for its album version.

The group signed to Echo Records and released their single "Where Is the What If the What Is in Why? Heather Phares of AllMusic described the sound of their debut album similar to that of Portishead and Massive Attack with elements of dance, funk, and trip hop, while noting the group had "a sense of humour and sass unique to Moloko. Moloko were not satisfied with the Terry mix and had to convince their label Echo Records to put out the Dlugosch version instead. Their third album Things to Make and Do was released in the year 2000 [6] and reached number three in the UK Albums Chart.
