It always amazes me whenever someone says that Heidi is their "favorite" Sugababe or is the "best" Sugababe. Her voice is sooooo weak and sooooo terrible. In the early days, she was the hot one and had an okay voice, but over the years her so-so voice has deteriorated. Just look at her weak showing in any live performance in the last 5 years. She's terrible, and Amelle isn't much better. Heidi and Amelle are the main reason why the Sugababes wouldn't make it here in the United States. We would boo them right off the stage with the wack Sugababes dancing (in all versions of the group) and the subpar vocals by Heidi and Amelle.
