Another promotion that didn't spend much time in the spotlight was the "Sade Ultimate Playlist Sweepstakes".

Originally made for Sony Music Entertainment, who wanted a "Sade Ultimate Playlist" promotion on social networking site Facebook to coincide with the 2011 release of The Ultimate Collection. This unique Facebook promotion features a personalized playlist of favorite Sade songs that fans can create and virally share on Facebook. The playlist application features snippets of all Sade songs that users can preview and add to their list, which is then shared directly in Facebook's newsfeed for their friends to interact with.  The promotion also features a contest open to UK and US-based fans, allowing them to enter to win a variety of prizes from Sade.
