Songs below were made by Ann Lee (aka Annerley Gordon -- she was the Whigfield vocalist for the first 4 albums)

Two Times
Hold my Hand
Emeralds - Do it for Love
A. Gordon - Say Yeah

Lover, as the singer of "Whigfield"
Gonna Getcha, as the singer of "Whigfield"

The difference is that for the Whigfield albums, her voice is strong and pitch is high, whereas when she sings as herself (Ann Lee), her voice is controlled, smooth and pitch is balanced.

You can do magic!
