#7 Omawumi
Omawumi, 30, is a past Idols West Africa finalist, whose debut single In The Music, became an instant hit in 2008.
In The Music, a Kwaito-driven song laced with subtle traces of Pidgin English, saw her top the charts for months.
In 2009, she released her much anticipated Wonder Woman album, which included the now-popular Ma Fi Mi Shere song.
