At the end of September 2010 Enigma's producer Michael Cretu officially announced a special event for the 20th anniversary of the project called "Enigma's Social Song" involving the fans all over the world.

The project was set up as an event "to commemorate Enigma's 20th anniversary involving fans actively in the process of creating a song together with Michael Cretu. For the first time ever he will allow people to look behind the scenes writing and producing along the preferences of the public. They will be engaged in original vocal submissions, series of votings and active participation. That's why we call it a "Social Song"."

Enigma's Social Song official website was also created.

The following 3 weeks hundreds of fans submitted and voted for their favorite vocals via YouTube. For the first two weeks of voting J. Spring's "Time Machine" was the fans favorite but Fox Lima's "Fei Mea" was eventually the most popular, and became the lead vocalist, closely followed by Mark Josher's "Set U Free", J. Spring's "Time Machine" and Rasa Serra's "Oi Giria Giria".
