I think Fergie is an underrated singer. She can sing in SO many styles and she nails each of the styles she sings (of those I've heard). For example, I heard two songs and really liked them both. And I thought, "Who are these female singers?" Then I found out both songs were by the same singer - - Fergie! Both songs -- VERY different styles/genres -- and she was SO solid on both! I like her voice. :)
