Given the following context:

By the first week of January 1999, Arnold completed the song's outline and made a synthesizer-arranged demo recording in his recording studio. He played the demo for Wilson, Broccoli and Apted, who were "extremely pleased" with the results. Arnold's agent then presented the demo to MGM executives in Los Angeles, who initially disliked it because it was a ballad and they expected a more uptempo song. MGM asked Arnold to rewrite a three-note sequence considered too similar to a motif in earlier Bond themes.That month Arnold offered the theme to Garbage lead singer Shirley Manson, who was very enthusiastic; Arnold said he "never heard someone screaming down the phone". A week later he sent the band the rough demo, which they approved. Manson requested a small change in the lyrics, disliking the line "I know when to kiss and I know when to kill", so Arnold and Black changed "I" to "we" for the final version.Garbage drummer and co-producer Butch Vig said that when the group contributed to film soundtracks, "one of our fantasies would be to do the Bond theme or do the new Bond song." Manson called herself a fan of the series, "an institution I admire and has always captured my imagination since I was a child", and the films had a "sensibility quite similar to how we approach making music". The chance to record a Bond theme appealed to her because "you know it's going down in movie history", and coming from Scotland, like original Bond Sean Connery, "that's very close and inherent in our culture. It's not Bond if it's not Scottish!" The singer considered Garbage's music and the series' concepts "something that you can enjoy on the surface, but underneath there are lots of conflicting themes you can get into."At the beginning of August Garbage's involvement was confirmed in a press release from MGM and Radioactive Records, Shirley Manson's record label, which would release the soundtrack and the single. Although Music Week reported that Jamiroquai, Robbie Williams, Sharleen Spiteri, Björk and Melanie C were rejected...
