She gained popularity success throughout the 1990s as the lead vocal performer of the German eurodance music group Fun Factory.
She moved to Hamburg in Germany where she met her future fellow Fun Factory band member Toni Cottura.
Before Fun Factory's third single release "Close to You" in 1993, Mey replaced lead singer Balca Tözün, who left the band and joined surviving founding members Rodney Hardison, Toni Cottura and Stephan Browarczyk.
With the second line-up, the band gained massive success, though it has been later revealed, that Tözün kept providing vocals in the background for all their later releases until their disbandment in 1997, with Mey just lip-syncing and performing with the group on stage[citation needed].
Mey started her side project in 1994 with the band Darkness, a group fronted by her and rapper Nana.
